  • Value isnt being saved in the strings

    - by Raptrex
    I'm trying to make a class where I put a key and value into the put method which puts the key in the k string array and value into the v string array, however it is not being saved in the array when I do get or display. For example: put(dan,30) get(dan) returns null display returns null null 10 times. Anyone know whats wrong? public class Memory { final int INITIAL_CAPACITY = 10; String[] k = new String[INITIAL_CAPACITY]; String[] v = new String[INITIAL_CAPACITY]; int count = 0; public Memory() { count = 0; } public int size() { return count; } public void put(String key, String value) { int a = 0; boolean found = false; for (int i = 0; i < k.length; i++) { //System.out.println("key is " + key.equals(k[i])); if (key.equalsIgnoreCase(k[i])) { v[i] = value; found = true; } if (found) break; a++; } //System.out.println(a == k.length); if (a == k.length); { k[count] = key; v[count] = value; //System.out.println(k[count] + " " + v[count]); count++; //System.out.println(count); } } public String get(String key) { String output = "a"; for(int i = 0; i < k.length; i++) { if(!key.equalsIgnoreCase(k[i])) { output = null; } else { output = v[i]; return output; } } return output; } public void clear() { for (int i = 0; i < k.length; i++) { k[i] = null; v[i] = null; } count = 0; } public void display() { for (int i = 0; i < k.length; i++) { System.out.println(k[i] + " " + v[i]); } } }

  • Custom annotations to configure tests

    - by ace
    First of al let me start off by saying I think custom annotations can be used for this but i'm not totally sure. I would like to have a set of annotations that I can decorate some test classes with. The annotations would allow me to configure the test for different environments. Example: public class Atest extends BaseTest{ private String env; @Login(environment=env) public void testLogin(){ //do something } @SignUp(environment=env) public void testSignUp(){ //do something } } The idea here would be that the login annotation would then be used to lookup the username and password to be used in the testLogin method for testing a login process for a particular environment. So my question(s) is this possible to do with annotations? If so I have not been able to find a decent howto online to do something like this. Everything out there seems to be your basic here's how to do your custom annotations and a basic processor but I haven't found anything for a situation like this. Ideas?

  • How to check whether the tab is active or not in JTabbedPane?

    - by Supereme
    Hi, How to check whether a tab in JTabbedPane instance is active or not, in the class of the tab(nested class) itself and not in the enclosing class? I know that there is a method 'booloean isEnabledAt(int index)'; but this method can only be called in the enclosing class whereas I want to check whether the tab is currently selected or not in the tab class (nested class) itself. Can anybody please suggest me something? Thank you!

  • What are the advantages of using J2EE over ASP.net?

    - by m_oLogin
    We are currently planning to launch a couple of internal web projects in the future. Our company's dev teams are mostly experienced in J2EE and have worked with it for years. Today, we have the choice of launching a couple of our projects on .net. I have checked out a couple of sources on the net, and it seems like the "J2EE vs ASP.net" combat brings out as much discord as the overseen "Apple vs Microsoft" or "Free Eclipse vs Visual Studio"... Nevertheless, I have been somewhat quite impressed with ASP.net's abilities to create great things with huge simplicity (for ex. asp.net ajax's demos). No more tons of xmls to play with, no more tons of frameworks to configure (we usually use the famous combo struts/spring/hibernate)... It just seemed to me that ASP.net had some good advantages over J2EE, but then again, I may speak by ignorance. What I want to know is this : What are the real advantages of using J2EE over ASP.net? Is there anything that cannot be done in ASP.net that can be done in J2EE? Once the frameworks are all in place and configured, is it faster to develop apps in J2EE than it is in .net? Are the applications generally easier to maintain in J2EE than in ASP.net? Is it worth it for some developpers to leave their J2EE knowledge on the side and move on to ASP.net if it does exactly the same thing?

  • Listener to prevent System.out display on the screen.

    - by harshit
    Hi, I was doing my academic project and while building and testing i have put many println() statements. But when I had to submit all prints should not be displayed. Can i implement something like listener which will be invoked when System.out is tried to be executed and prevents it from displaying. I dont know how feasible this idea is but just want to know whether its possible or not. I know i could have used a log file or write into a file but again its just a thought came into my mind if I have to disable SOP how can i do it .. thanks

  • Create a buffered image from rgb pixel values

    - by Jeff Storey
    I have an integer array of RGB pixels that looks something like: pixels[0] = <rgb-value of pixel(0,0)> pixels[1] = <rgb-value of pixel(1,0)> pixels[2] = <rgb-value of pixel(2,0)> pixels[3] = <rgb-value of pixel(0,1)> ...etc... And I'm trying to create a BufferedImage from it. I tried the following: BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); img.getRaster().setPixels(0, 0, width, height, pixels); But the resulting image has problems with the color bands. The image is unclear and there are diagonal and horizontal lines through it. What is the proper way to initialize the image with the rgb values? thanks, Jeff

  • JFreeChart Ugly Rounding Error?

    - by billynomates
    Using series.add(180, 1); produces a perfectly valid chart like this (little red dot at the bottom with some PolarItemRenderer Mods!) but using series.add(3000/(6000/360), 1); produces this beast: I assume it's because somewhere, 6000/360 = 16.6... is getting rounded? How can I stop this happening? Thanks :)

  • Hibernate: how to maintain insertion order

    - by jwaddell
    I have a list of entities where creation order is important, but they do not contain a timestamp to use for sorting. Entities are added to the end of the list as they are created so they will be ordered correctly in the list itself. After persisting the list using Hibernate the entities appear in the database table in the order that they were created. However when retrieving the list using a new Hibernate session the list is now in reverse order of insertion/creation. Is this expected behaviour? Is there any way to retrieve the list in the same order as it appears in the table? The primary key is a UUID, and the list of entities should always have been created on the same IP address and JVM. This mean sorting by UUID is a possibility but I'd rather not make assumptions. Another possibility is if the list is guaranteed to always come out in reverse order I could always just work through it backwards.

  • Androids ExpandableListView - where to put the button listener for buttons that are children

    - by CommonKnowledge
    I have been playing around a lot with the ExpandableListView and I cannot figure out where to add the button listeners for the button that will be the children in the view. I did manage to get a button listener working that uses getChildView() below, but it seems to be the same listener for all the buttons. The best case scenario is that I would be able to implement the button listeners in the class that instantiates the ExpandableListAdapter class, and not have to put the listeners in the actual ExpandableListAdapter class. At this point I don't even know if that is possible I have been experimenting with this tutorial/code: HERE getChildView() @Override public View getChildView(int set_new, int child_position, boolean view, View view1, ViewGroup view_group1) { ChildHolder childHolder; if (view1 == null) { view1 = LayoutInflater.from(info_context).inflate(R.layout.list_group_item_lv, null); childHolder = new ChildHolder(); childHolder.section_btn = (Button)view1.findViewById(R.id.item_title); view1.setTag(childHolder); childHolder.section_btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(info_context, "button pushed", Toast.LENGTH_SHORT).show(); } }); }else { childHolder = (ChildHolder) view1.getTag(); } childHolder.section_btn.setText(children_collection.get(set_new).GroupItemCollection.get(child_position).section); Typeface tf = Typeface.createFromAsset(info_context.getAssets(), "fonts/AGENCYR.TTF"); childHolder.section_btn.setTypeface(tf); return view1; } Any help would be much appreciated. Thank you and I will be standing by.

  • Hibernate/JPA - annotating bean methods vs fields

    - by Benju
    I have a simple question about usage of Hibernate. I keep seeing people using JPA annotations in one of two ways by annotating the fields of a class and also by annotating the get method on the corresponding beans. My question is as follows: Is there a difference between annotating fields and bean methods with JPA annoations such as @Id. example: @Entity public class User { **@ID** private int id; public int getId(){ return this.id; } public void setId(int id){ this.id=id; } } -----------OR----------- @Entity public class User { private int id; **@ID** public int getId(){ return this.id; } public void setId(int id){ this.id=id; } }

  • Changing an Action Type="click" to an auto action in SVG

    - by Dustin Myers
    I have a SVG document that I exported from Visio 2003 that would like to edit. This file has an action where you click a button it will navigate to a new screen. What I would like to do is have the navigation be based off of a data point rather than having to click the button. As an example I have a dynamic point data being brought into the SVG file and when that value changes from 0 to 1, I want this screen to automatically navigate to another screen. Below is the code I for clicking the button. <title content="structured text">Sheet.1107</title> <desc content="structured text">Button 1</desc> <v:custProps> <v:cp v:ask="false" v:langID="1033" v:invis="false" v:cal="0" v:val="VT4(Test Graphic 2)" v:type="0" v:prompt="" v:nameU="ObjRef" v:sortKey="" v:lbl="" v:format=""/> <v:cp v:ask="false" v:langID="1033" v:invis="false" v:cal="0" v:val="VT4(SF-S)" v:type="0" v:prompt="" v:nameU="DataPt" v:sortKey="" v:lbl="" v:format=""/> </v:custProps> <v:userDefs> <v:ud v:prompt="" v:nameU="NAVIGATE" v:val="VT4(NAVIGATE Test Graphic 2,&apos;&apos;,)"/> </v:userDefs> <v:textBlock v:margins="rect(4,4,4,4)"/> <v:textRect width="125.01" height="35" cx="62.5" cy="517.5"/> <rect x="0" width="125" y="500" height="35" class="st3"/> <text x="40.15" y="521.1" v:langID="1033" class="st4"><v:paragraph v:horizAlign="1"/><v:tabList/>Button 1</text> <jci:action type="click" count="1">if(evt.button == 0) nav(&apos;Test Graphic 2&apos;,&apos;&apos;,&apos;&apos;);</jci:action></g></a> In the above code I am bringing in the data value from SF-S. Once that value is equal to 1 I want this screen to automatically navigate to Test Graphic 2. I don't have any experience with coding so I am hoping someone here will be able to help me. Thanks, DMyers

  • Help naming a class that has a single public method called Execute()

    - by devoured elysium
    I have designed the following class that should work kind of like a method (usually the user will just run Execute()): public abstract class ??? { protected bool hasFailed = false; protected bool hasRun = false; public bool HasFailed { get { return hasFailed; } } public bool HasRun { get { return hasRun; } } private void Restart() { hasFailed = false; hasRun = false; } public bool Execute() { ExecuteImplementation(); bool returnValue = hasFailed; Restart(); return returnValue; } protected abstract void ExecuteImplementation(); } My question is: how should I name this class? Runnable? Method(sounds awkward)?

  • Spring vs Hibernate

    - by Vidar
    Just trying to get my head round Spring and figuring out how I wire up an Oracle connection in xml config file, and now find out I need yet another framework! - Hibernate, this is soooo frustrating as it feels like I'm getting deeper and deeper into more and more frameworks without actually getting what I need done! I looked at Hibernate and it seems to do similar things to Spring, bearing in mind I just want to do some SQL inserts in Oracle. I am reluctant and do not have time to learn 2 frameworks - could I get away with just adopting Hibernate for the simple things I need to do?
