  • Django: Named URLs / Same Template, Different Named URL

    - by TheLizardKing
    I have a webapp that lists all of my artists, albums and songs when the appropriate link is clicked. I make extensive use of generic views (object_list/detail) and named urls but I am coming across an annoyance. I have three templates that pretty much output the exact same html that look just like this: {% extends "base.html" %} {% block content %} <div id="content"> <ul id="starts-with"> {% for starts_with in starts_with_list %} <li><a href="{% url song_list_x starts_with %}">{{ starts_with|upper }}</a></li> {% endfor %} </ul> <ul> {% for song in songs_list %} <li>{{ song.title }}</li> {% endfor %} </ul> </div> {% endblock content %} My artist and album template look pretty much the same and I'd like to combine the three template's into one. The fact that my variables start with song can easily be changed to the default obj. It's my <ul id="starts-with"> named url I don't know how to correct. Obviously I want it to link to a specific album/artist/song using the named urls in my urls.py but I don't know how to make it context aware. Any suggestions? urlpatterns = patterns('tlkmusic.apps.tlkmusic_base.views', # (r'^$', index), url(r'^artists/$', artist_list, name='artist_list'), url(r'^artists/(?P<starts_with>\w)/$', artist_list, name='artist_list_x'), url(r'^artist/(?P<artist_id>\d+)/$', artist_detail, name='artist_detail'), url(r'^albums/$', album_list, name='album_list'), url(r'^albums/(?P<starts_with>\w)/$', album_list, name='album_list_x'), url(r'^songs/$', song_list, name='song_list'), url(r'^songs/(?P<starts_with>\w)/$', song_list, name='song_list_x'), )

  • Object oriented design of game in Java: How to handle a party of NPCs?

    - by Arvanem
    Hi folks, I'm making a very simple 2D RPG in Java. My goal is to do this in as simple code as possible. Stripped down to basics, my class structure at the moment is like this: Physical objects have an x and y dimension. Roaming objects are physical objects that can move(). Humanoid objects are roaming objects that have inventories of GameItems. The Player is a singleton humanoid object that can hire up to 4 NPC Humanoids to join his or her party, and do other actions, such as fight non-humanoid objects. NPC Humanoids can be hired by the Player object to join his or her party, and once hired can fight for the Player. So far I have given the Player class a "party" ArrayList of NPC Humanoids, and the NPC Humanoids class a "hired" Boolean. However, my fight method is clunky, using an if to check the party size before implementing combat, e.g. public class Player extends Humanoids { private ArrayList<Humanoids> party; // GETTERS AND SETTERS for party here //... public void fightEnemy(Enemy eneObj) { if (this.getParty().size() == 0) // Do combat without party issues else if (this.getParty().size() == 1) // Do combat with party of 1 else if (this.getParty().size() == 2) // Do combat with party of 2 // etc. My question is, thinking in object oriented design, am I on the right track to do this in as simple code as possible? Is there a better way?

  • Java - Class type from inside static initialization block

    - by DutrowLLC
    Is it possible to get the class type from inside the static initialization block? This is a simplified version of what I currently have:: class Person extends SuperClass { String firstName; static{ // This function is on the "SuperClass": // I'd for this function to be able to get "Person.class" without me // having to explicitly type it in but "this.class" does not work in // a static context. doSomeReflectionStuff(Person.class); // IN "SuperClass" } } This is closer to what I am doing, which is to initialize a data structure that holds information about the object and its annotations, etc... Perhaps I am using the wrong pattern? public abstract SuperClass{ static void doSomeReflectionStuff( Class<?> classType, List<FieldData> fieldDataList ){ Field[] fields = classType.getDeclaredFields(); for( Field field : fields ){ // Initialize fieldDataList } } } public abstract class Person { @SomeAnnotation String firstName; // Holds information on each of the fields, I used a Map<String, FieldData> // in my actual implementation to map strings to the field information, but that // seemed a little wordy for this example static List<FieldData> fieldDataList = new List<FieldData>(); static{ // Again, it seems dangerous to have to type in the "Person.class" // (or Address.class, PhoneNumber.class, etc...) every time. // Ideally, I'd liken to eliminate all this code from the Sub class // since now I have to copy and paste it into each Sub class. doSomeReflectionStuff(Person.class, fieldDataList); } }

  • Linking AS code to symbols defined in an external SWC?

    - by Ender
    (apologies ahead of time, I only really know Flash; my Flex experience is basically nil. There may be a very standard and obvious workflow solution that Flex people know about) I have a number of UI elements that are graphically quite complex (they're not components, they're just Sprites). Since it takes a long time to compile them, I've been trying to move them into an external .swc. However, I want to associate some code with these classes, but I don't want to have to recompile the graphical assets every time I make a code change. At the moment I have it set up like this: UI elements are created in a separate FLA and exported to a SWC. In my primary FLA, I have actionscript classes that extend each of the graphical assets in the SWC. For example: external.swc: (some symbol defined in the Library and exported for actionscript in frame 1) class: com.foo.WidgetGraphic base: flash.display.Sprite main.fla: Widget.as: package com.foo { public class Widget extends WidgetGraphic { ... } } This works, but is time-consuming and prone to error. I'd rather be able to avoid having to inherit from each graphical asset, and just define them directly. Is there a better way to do what I'm trying to accomplish? Note: the main concern here is compile time. I don't have any movies or audio or fonts, just a lot of vector art assets that appear to be slowing down my compilation time significantly. When I'm debugging I'm only making code changes, and would rather not have to keep recompiling the art...

  • ExternalInterface

    - by Jesse
    Hey, so I'm having a bunch of trouble getting ExternalInterface to work, which is odd, because I use it somewhat often. I'm hoping it's something I just missed because I've been looking at it too long. The flash_ready function is correctly returning the objectID, and as far as I can tell, everything else is in order. Unfortunately, when I run it, I get an error (varying by browser) telling me that basically document.getElementById(<movename>).test() is not a valid method. Here's the code: javascript: function flash_ready(i){ document.getElementById(i).test('success!'); } Embed Html (Generated): <script type="text/javascript"> swfobject.embedSWF("/chainmaille/includes/media/flash/upload_image.swf", "/chainmaille/includes/media/flash/upload_image", "500", "50", "9.0.0","expressInstall.swf", {}, {allowScriptAccess:'always', wmode:'transparent'},{id:'uploader_flash',name:'uploader_flash'}); </script> <object type="application/x-shockwave-flash" id="uploader_flash" name="uploader_flash" data="/chainmaille/includes/media/flash/upload_image.swf" width="500" height="50"><param name="allowScriptAccess" value="always"><param name="wmode" value="transparent"></object> AS3 : package com.jesseditson.uploader { import flash.display.MovieClip; import flash.external.ExternalInterface; import flash.system.Security; public class UI extends MovieClip { // Initialization: public function UI() { Security.allowDomain('*'); ExternalInterface.addCallback("test", test); var jscommand:String = "flash_ready('"+ExternalInterface.objectID+"');"; var url:URLRequest = new URLRequest("javascript:" + jscommand + " void(0);"); navigateToURL(url, "_self"); } public function test(t){ trace(t); } } } Swfobject is being included via google code, and the flash embeds just fine, so that's not the problem. I've got a very similar setup working on another server, but can't seem to get it working on this one. It's a Hostgator shared server. Could it be the server's fault? Anybody see any obvious syntax problems? Thanks in advance!

  • How do I relate tables with different foreign key names in Kohana ORM?

    - by Matt H
    I'm building a Kohaha application to manage sip lines in asterisk. I'm wanting to use ORM but I'm wondering how do relate certain tables that are already well established. e.g. the table sip_lines looks like this. +--------------------+------------------+------+-----+-------------------+-----------------------------+ | Field | Type | Null | Key | Default | Extra | +--------------------+------------------+------+-----+-------------------+-----------------------------+ | id | int(10) unsigned | NO | PRI | NULL | auto_increment | | sip_name | varchar(80) | NO | UNI | NULL | | | displayname | varchar(48) | NO | | NULL | | | line_num | varchar(10) | NO | MUL | NULL | | | model | varchar(12) | NO | MUL | NULL | | | mac | varchar(16) | NO | MUL | NULL | | | areacode | varchar(6) | NO | MUL | NULL | | | per_line_astpp_acc | tinyint(1) | NO | | 0 | | | play_warning | tinyint(1) | NO | | 0 | | | callout_disabled | tinyint(1) | NO | | 0 | | | notes | varchar(80) | NO | | NULL | | | last_update | timestamp | NO | | CURRENT_TIMESTAMP | on update CURRENT_TIMESTAMP | +--------------------+------------------+------+-----+-------------------+-----------------------------+ sip_buddies is this: +----------------+------------------------------+------+-----+-----------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+------------------------------+------+-----+-----------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | name | varchar(80) | NO | UNI | | | | host | varchar(31) | NO | | | | | | | lastms | int(11) | NO | | 0 *** snip *** +----------------+------------------------------+------+-----+-----------+----------------+ The two tables are actually related as sip_lines.sip_name = sip_buddies.name How do I relate them in Kohana ORM as this wouldn't be quite right would it? <?php defined('SYSPATH') or die('No direct script access.'); /* A model for all the account information */ class Sip_Line_Model extends ORM { protected $has_one = array("sip_buddies"); } ?> EDIT: Actually, it'd be fair to say that these tables are not properly related with foreign keys! doh. EDIT: Looks like Kohana ORM is not that flexible. ORM is probably not the way to go and works best for completely new projects where the data model can be altered. The reason being that the key names must follow a specific naming convention or else they won't relate in Kohana.

  • django html/css windows mac problem width additional space on the top of the page

    - by rafal
    Hi, my problem is really strange... We are developing shopping-cart system in django. The problem is, when I change anything even single letter on my computer, strange space on the top of the page appears, see the picture... I don't know since when the problem appears. But if i go back to previous version (in this case 210, we use svn), everything is ok, until i change something. I'm using windows 7 and i tried to edit this file in notepad, notepad++, e and so on... In the case when my friend changes something in this 210 version on Macbook everything is ok. Have anyone any ideas? Also in source code of the page strange "-" is added before doctype, but it is only visible in chrome. But the problem is for all browsers...! what is more... for example my home page extends, categories.html and base.html, and in this case a have two "--". Of course If i change something in this two files base and home... PLEASE HELP!:) http://img402.imageshack.us/img402/5655/buguh.png [2]:

  • Dispatch request to an Async Servlet from managed bean generate exception

    - by Thang Pham
    when a button click, I need to have stuff running in my background, so I have a async Servlet. From my managed bean, if I do redirect, it works great (meaning that it execute my run() method inside my class that extends Runnable correctly). Like this String url = externalContext.getRequestContextPath() + "/ReportExecutionServlet"; externalContext.redirect(url); But if I switch to dispatch, like this externalContext.redirect("/ReportExecutionServlet"); it fail when I try to obtain the AsyncContext AsyncContext aCtx = request.startAsync(request, response); The error is below Caused By: java.lang.IllegalStateException: The async-support is disabled on this request: weblogic.servlet.internal.ServletRequestImpl Any idea how to fix this please? NOTE: This is how to execute my async servlet, just in case: AsyncContext aCtx = request.startAsync(request, response); //delegate long running process to an "async" thread aCtx.addListener(new AsyncListener() { @Override public void onComplete(AsyncEvent event) throws IOException { logger.log(Level.INFO, "ReportExecutionServlet handle async request - onComplete"); } @Override public void onTimeout(AsyncEvent event) throws IOException { logger.log(Level.WARNING, "ReportExecutionServlet handle async request - onTimeout"); } @Override public void onError(AsyncEvent event) throws IOException { logger.log(Level.SEVERE, "ReportExecutionServlet handle async request - onError"); } @Override public void onStartAsync(AsyncEvent event) throws IOException { logger.log(Level.INFO, "ReportExecutionServlet handle async request - onStartAsync"); } }); // Start another service ScheduledThreadPoolExecutor executor = new ScheduledThreadPoolExecutor(10); executor.execute(new AsyncRequestReportProcessor(aCtx));

  • addNotify not works allright

    - by joseph
    Hello. I call addNotify() method in class that I posted here. The problem is, that when I call addNotify() as it is in the code, setKeys(objs) do nothing. Nothing appears in my explorer of running app. But when I call addNotify()without loop(for int....), and add only one item to ArrayList, it shows that one item correctly. Does anybody knows where can be problem? See the cede class ProjectsNode extends Children.Keys{ private ArrayList objs = new ArrayList(); public ProjectsNode() { } @Override protected Node[] createNodes(Object o) { MainProject obj = (MainProject) o; AbstractNode result = new AbstractNode (new DiagramsNode(), Lookups.singleton(obj)); result.setDisplayName (obj.getName()); return new Node[] { result }; } @Override protected void addNotify() { //this loop causes nothing appears in my explorer. //but when I replace this loop by single line "objs.add(new MainProject("project1000"));", it shows that one item in explorer for (int i=0;i==10;i++){ objs.add(new MainProject("project1000")); } setKeys (objs); } }

  • how to continuously send data without blocking?

    - by Donal Rafferty
    I am trying to send rtp audio data from my Android application. I currently can send 1 RTP packet with the code below and I also have another class that extends Thread that listens to and receives RTP packets. My question is how do I continuously send my updated buffer through the packet payload without blocking the receiving thread? public void run() { isRecording = true; android.os.Process.setThreadPriority (android.os.Process.THREAD_PRIORITY_URGENT_AUDIO); int buffersize = AudioRecord.getMinBufferSize(8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); Log.d("BUFFERSIZE","Buffer size = " + buffersize); arec = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize); short[] readBuffer = new short[80]; byte[] buffer = new byte[160]; arec.startRecording(); while(arec.getRecordingState() == AudioRecord.RECORDSTATE_RECORDING){ int frames = arec.read(readBuffer, 0, 80); @SuppressWarnings("unused") int lenghtInBytes = codec.encode(readBuffer, 0, buffer, frames); RtpPacket rtpPacket = new RtpPacket(); rtpPacket.setV(2); rtpPacket.setX(0); rtpPacket.setM(0); rtpPacket.setPT(0); rtpPacket.setSSRC(123342345); rtpPacket.setPayload(buffer, 160); try { rtpSession2.sendRtpPacket(rtpPacket); } catch (UnknownHostException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (RtpException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } So when I send on one device and receive on another I get decent audio, but when I send and receive on both I get broken sound like its taking turns to send and receive audio. I have a feeling it could be to do with the while loop? it could be looping around in there and not letting anything else run?

  • Cakephp ACL authentication issue - I'm locked out

    - by Baseer
    I've followed the CakePHP Cookbook ACL tutorial And as of right now I'm just trying to add users using the scaffolding method. I'm trying to go to /users/add but it always redirects me to the login screen even though I have added $this->Auth->allow('*'); in beforeFilter() temporarily to allow access to all pages. I've done this in both the UsersController and GroupsController as the tutorial asked. Below is my code for UsersController which I think will be the most relevant of all the files. Let me know if any other piece of code is required. <?php class UsersController extends AppController { var $name = 'Users'; var $scaffold; function beforeFilter() { parent::beforeFilter(); $this->Auth->allow('*'); } function login() { //Auth Magic } function logout() { //Leave empty for now. } } ?> I think I've pretty much followed the tutorial, any ideas as to what I may be missing? Thanks. I've been stuck on this for a while. =(

  • Java Swing Threading with Updatable JProgressBar

    - by Anthony Sparks
    First off I've been working with Java's Concurency package quite a bit lately but I have found an issue that I am stuck on. I want to have and Application and the Application can have a SplashScreen with a status bar and the loading of other data. So I decided to use SwingUtilities.invokeAndWait( call the splash component here ). The SplashScreen then appears with a JProgressBar and runs a group of threads. But I can't seem to get a good handle on things. I've looked over SwingWorker and tried using it for this purpose but the thread just returns. Here is a bit of sudo-code. and the points I'm trying to achieve. Have an Application that has a SplashScreen that pauses while loading info Be able to run multiple threads under the SplashScreen Have the progress bar of the SplashScreen Update-able yet not exit until all threads are done. Launching splash screen try { SwingUtilities.invokeAndWait( SplashScreen ); } catch (InterruptedException e) { } catch (InvocationTargetException e) { } Splash screen construction SplashScreen extends JFrame implements Runnable{ public void run() { //run threads //while updating status bar } } I have tried many things including SwingWorkers, Threads using CountDownLatch's, and others. The CountDownLatch's actually worked in the manner I wanted to do the processing but I was unable to update the GUI. When using the SwingWorkers either the invokeAndWait was basically nullified (which is their purpose) or it wouldn't update the GUI still even when using a PropertyChangedListener. If someone else has a couple ideas it would be great to hear them. Thanks in advance.

  • Flex - Increase timeout on a PHP service function call

    - by Travesty3
    I'm using Flash Builder 4 Beta 2. I have it connecting to a PHP service. The way I set this up was using the wizard, so I didn't actually write the code to connect to it. The service looks like this: package services.flash { import mx.rpc.AsyncToken; import com.adobe.fiber.core.model_internal; import mx.rpc.AbstractOperation; import valueObjects.CustomDatatype8; import valueObjects.NewUsageData; import mx.collections.ItemResponder; import mx.rpc.remoting.RemoteObject; import mx.rpc.remoting.Operation; import com.adobe.fiber.services.wrapper.RemoteObjectServiceWrapper; import com.adobe.fiber.valueobjects.AvailablePropertyIterator; import com.adobe.serializers.utility.TypeUtility; [ExcludeClass] internal class _Super_FLASH extends RemoteObjectServiceWrapper { // Constructor public function _Super_FLASH() { // initialize service control _serviceControl = new RemoteObject(); var operations:Object = new Object(); var operation:Operation; operation = new Operation(null, "sendCommand"); operation.resultType = Object; operations["sendCommand"] = operation; ... } } One of the functions that I'm calling fetches users from a MySQL database. There are about 30,000 users right now. The service seems to timeout when fetching more than around 22,000 rows, I get the "Channel Disconnected before an acknowledgement was received" error. If I call the PHP script from a browser, it fetches them all with no problems at all, however. I have tried increasing the timeout in the PHP script (which didn't work), but obviously this isn't the problem since the browser is able to pull them up with no problems. Is there a way to increase the timeout of the PHP service in Flash Builder? I'm a bit of a noob when it comes to Flash, so please be descriptive. Thanks in advance!

  • Why is Collection<String>.class Illegal?

    - by Peter
    I am puzzled by generics. You can declare a field like: Class<Collection<String>> clazz = ... It seems logical that you could assign this field with: Class<Collection<String>> clazz = Collection<String>.class; However, this generates an error: Syntax error on token ">", void expected after this token So it looks like the .class operator does not work with generics. So I tried: class A<S> {} class B extends A<String> {} Class<A<String>> c = B.class; Also does not work, generates: Type mismatch: cannot convert from Class<Test.StringCollection> to Class<Collection<String>> Now, I really fail to see why this should not work. I know generic types are not reified but in both cases it seems to be fully type safe without having access to runtime generic types. Anybody an idea? Peter Kriens

  • Is 1/0 a legal Java expression?

    - by polygenelubricants
    The following compiles fine in my Eclipse: final int j = 1/0; // compiles fine!!! // throws ArithmeticException: / by zero at run-time Java prevents many "dumb code" from even compiling in the first place (e.g. "Five" instanceof Number doesn't compile!), so the fact this didn't even generate as much as a warning was very surprising to me. The intrigue deepens when you consider the fact that constant expressions are allowed to be optimized at compile time: public class Div0 { public static void main(String[] args) { final int i = 2+3; final int j = 1/0; final int k = 9/2; } } Compiled in Eclipse, the above snippet generates the following bytecode (javap -c Div0) Compiled from "Div0.java" public class Div0 extends java.lang.Object{ public Div0(); Code: 0: aload_0 1: invokespecial #8; //Method java/lang/Object."<init>":()V 4: return public static void main(java.lang.String[]); Code: 0: iconst_5 1: istore_1 // "i = 5;" 2: iconst_1 3: iconst_0 4: idiv 5: istore_2 // "j = 1/0;" 6: iconst_4 7: istore_3 // "k = 4;" 8: return } As you can see, the i and k assignments are optimized as compile-time constants, but the division by 0 (which must've been detectable at compile-time) is simply compiled as is. javac 1.6.0_17 behaves even more strangely, compiling silently but excising the assignments to i and k completely out of the bytecode (probably because it determined that they're not used anywhere) but leaving the 1/0 intact (since removing it would cause an entirely different program semantics). So the questions are: Is 1/0 actually a legal Java expression that should compile anytime anywhere? What does JLS say about it? If this is legal, is there a good reason for it? What good could this possibly serve?

    Hi All - I am still a bit of a beginner at AS3, so bear with me, please. I have created a loop to instantiate tiles on a board. In the following example, "Gametiles" is an array containing objects of class "Tile" which is a class that extends MovieClip. "Game" is a MC that I added to the stage in the flash developing environment. for(var i:uint=0;i < Gametiles.length;i++){ var pulledTile = Gametiles[i]; var tilename:String = "I_Tile_" + pulledTile.grid_y + "_" + pulledTile.grid_x; var createdTile = new InteractiveTile(); pulledTile.addAnims(createdTile); Game.addChildAt(pulledTile, 0); Game.getChildAt(0).name = tilename; } The above code works - but with a tricky problem. If I did something like the following: trace(Game.I_Tile_1_3.x); I get "TypeError: Error #1010: A term is undefined and has no properties." However, I am able to access theses children in the following manner: var testing = Game.getChildByName("I_Tile_1_3") trace(testing.x); This method is a bit cumbersome though. I really don't want to have to create a var and call getChildByName every time I want to interact with these properties or methods. How can I set up these children so that I can access them directly without the extra steps?

  • code igniter codeigniter question, making anchor load page containing data from referenced row in DB

    - by thrice801
    Hi, Im trying to learn the code igniter library and object oriented php in general and have a question. Ok so Ive gotten as far as making a page which loads all of the rows from my database and in there, Im echoing an anchor tag which is a link to the following structure. [code]echo anchor("videos/video/$row-video_id", $row-video_title);[/code] So, I have a class called Videos which extends the controller, within that class there is index and video, which is being called correctly (when you click on the video title, it sends you to videos/video/5 for example, 5 being the primary key of the table im working with. So basically all Im trying to do is pass that 5 back to the controller, and then have the particular video page output the particular rows data from the videos table. My function in my controller for video looks like this - [code] function video() { $data['main_content'] = 'video'; $data['video_title'] = 'test'; $this-load-view('includes/template', $data); } [/code] So ya, basically test should be instead of test, a returned value of a query which says get in the table "videos", the row with the video_id of "5", and make $data['video_title'] = value of video_title in database... Should have this figured out by now but dont, any help would be appreciated!

  • identifying id of listitem for contextmenu

    - by martinjd
    I have a View that extends Activity. A ListView will display a number of listitems. When the user long clicks I would like to present them with a contextmenu allowing them to select edit, delete etc... and then identify the listitem that was selected as the item to perform the action on. In onCreate I have: listView.setAdapter(adapter); listView.setOnItemClickListener(onListClick); listView.setOnItemLongClickListener(onListLongClick); registerForContextMenu(listView); I have a method onCreateContextMenu @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.setHeaderTitle("Context Menu"); menu.add(0, v.getId(), 0, "Edit"); menu.add(0, v.getId(), 0, "Delete"); } and also onContextItemSelected @Override public boolean onContextItemSelected(MenuItem item) { if (item.getTitle() == "Edit") { // edit action } else if (item.getTitle() == "Delete") { // delete action } else { return false; } return true; } I am not sure where to go from here to get the correct row/listitem.

  • Java and dynamic variables

    - by Arvanem
    Hi folks, I am wondering whether it is possible to make dynamic variables in Java. In other words, variables that change depending on my instructions. FYI, I am making a trading program. A given merchant will have an array of items for sale for various prices. The dynamism I am calling for comes in because each category of items for sale has its own properties. For example, a book item has two properties: int pages, and boolean hardCover. In contrast, a bookmark item has one property, String pattern. Here are skeleton snippets of code so you can see what I am trying to do: public class Merchants extends /* certain parent class */ { // only 10 items for sale to begin with Stock[] itemsForSale = new Stock[10]; // Array holding Merchants public static Merchants[] merchantsArray = new Merchants[maxArrayLength]; // method to fill array of stock goes here } and public class Stock { int stockPrice; int stockQuantity; String stockType; // e.g. book and bookmark // Dynamic variables here, but they should only be invoked depending on stockType int pages; boolean hardCover; String pattern; }

  • Java Generic Casting Type Mismatch

    - by Kay
    public class MaxHeap<T extends Comparable<T>> implements Heap<T>{ private T[] heap; private int lastIndex; public void main(String[] args){ int i; T[] arr = {1,3,4,5,2}; //ERROR HERE ******* foo } public T[] Heapsort(T[]anArray, int n){ // build initial heap T[]sortedArray = anArray; for (int i = n-1; i< 0; i--){ //assert: the tree rooted at index is a semiheap heapRebuild(anArray, i, n); //assert: the tree rooted at index is a heap } //sort the heap array int last = n-1; //invariant: Array[0..last] is a heap, //Array[last+1..n-1] is sorted for (int j=1; j<n-1;j++) { sortedArray[0]=sortedArray[last]; last--; heapRebuild(anArray, 0, last); } return sortedArray; } protected void heapRebuild(T[ ] items, int root, int size){ foo } } The error is on the line with "T[arr] = {1,3,4,5,2}" Eclispe complains that there is a: "Type mismatch: cannot convert from int to T" I've tried to casting nearly everywhere but to no avail.A simple way out would be to not use generics but instead just ints but that's sadly not an option. I've got to find a way to resolve the array of ints "{1,3,4,5,2}" into an array of T so that the rest of my code will work smoothly.
