  • Java: global values inside a class?

    - by HH
    I want less methods. I want a common global TestClass from which I could use any of its value inside the class. import java.util.*; import java.io.*; public class TestClass { TestClass(String hello){ String hallo = hello; String halloSecond = "Saluto!"; } public static void main(String[] args) { TestClass test = new TestClass("Tjena!"); System.out.println("I want "Tjena!": " + test.hallo); TestClass testSecond = new TestClass("1"); System.out.println("I want Saluto!:" + test.halloSecond); System.out.println("I want Saluto!:" + testSecond.halloSecond); } }

  • Java date processing

    - by Don
    Hi, Given an instance of java.util.Date which is a Sunday. If there are 4 Sundays in the month in question, I need to figure out whether the chosen date is 1st Sunday of month 2nd Sunday of month 2nd last Sunday of month Last Sunday of month If there are 5 Sundays in the month in question, then I need to figure out whether the chosen date is 1st Sunday of month 2nd Sunday of month 3rd Sunday of month 2nd last Sunday of month Last Sunday of month I've had a look in JodaTime, but haven't found the relevant functionality there yet. The project is actually a Groovy project, so I could use either Java or Groovy to solve this. Thanks, Donal

  • The standard map/associative-array structure to use in flash actionscript 3?

    - by tstyle
    I'm relatively new to flash, and is confused about what I should use to store and retrieve key value pairs. After some googling I've found various map-like things to choose from: 1) Use a Object: var map:Object = new Object(); map["key"] = "value"; The problem is that it seems to lack some very basic features. For example to even get the size of map I'd have to write a util method. 2) Use a Dictionary What does this standard library class provide over the simple object? It seems silly for it to exist if it's functionally identical to Object. 3) Go download some custom HashMap/HashTable implementation from the web. I've used a lot of modern languages, and this is the first time I haven't been able to find a library implementation of an associative array within 5 minutes. So I'd like to get some best-practice advice from an experienced flash developer. Thanks!

  • Android Read contents of a URL (content missing after in result)

    - by josnidhin
    I have the following code that reads the content of a url public static String DownloadText(String url){ StringBuffer result = new StringBuffer(); try{ URL jsonUrl = new URL(url); InputStreamReader isr = new InputStreamReader(jsonUrl.openStream()); BufferedReader in = new BufferedReader(isr); String inputLine; while ((inputLine = in.readLine()) != null){ result.append(inputLine); } }catch(Exception ex){ result = new StringBuffer("TIMEOUT"); Log.e(Util.AppName, ex.toString()); } in.close(); isr.close(); return result.toString(); } The problem is I am missing content after 4065 characters in the result returned. Can someone help me solve this problem. Note: The url I am trying to read contains a json response so everything is in one line I think thats why I am having some content missing.

  • YUI Image Loader Images Above Fold Not Loading Until Scroll event.

    - by Mike
    I have a function that is called on the window.onload event to create a group of images and render via the scroll event. function LoadImages(){ var foldGroup = new YAHOO.util.ImageLoader.group(window, 'scroll'); for(var i=0; i<someCounter; i++){ var locationId = locationsArr[i]; foldGroup.registerSrcImage('Location_' + locationId, GetImageDomain()+'/templates/Includes/imagehandler.ashx?locationId=' + locationid); } foldGroup.foldConditional = true; foldGroup.addTrigger(window, 'resize'); } The problem I'm having is that when the page loads, the images "above the fold" are not rendered until I scroll. Is there any tips on troubleshooting this? I'm totally not a js/frontend guy :) Thanks in advance!

  • Call 32-bit or 64-bit program from bootloader

    - by user1002358
    There seems to be quite a lot of identical information on the Internet about writing the following 3 bootloaders: Infinite loop jmp $ Print a single character Print "Hello World". This is fantastic, and I've gone through these 3 variations with very little trouble. I'd like to write some 32- or 64-bit code in C and compile it, and call that code from the bootloader... basically a bootloader that, for example, sets the computer up to run some simple numerical simulation. I'll start by listing primes, for example, and then maybe some input/output from the user to maybe compute a Fourier transform. I don't know. I haven't found any information on how to do this, but I can already foresee some problems before I even begin. First of all, compiling a C program compiles it into one of several different files, depending on the target. For Windows, it's a PE file. For Linux, it's a .out file. These files are both quite different. In my instance, the target isn't Windows or Linux, it's just whatever I have written in the bootloader. Secondly, where would the actual code reside? The bootloader is exactly 512 bytes, but the program I write in C will certainly compile to something much larger. It will need to sit on my (virtual) hard disk, probably in some sort of file system (which I haven't even defined!) and I will need to load the information from this file into memory before I can even think about executing it. But from my understanding, all this is many, many orders of magnitude more complex than a 12-line "Hello World" bootloader. So my question is: How do I call a large 32- or 64-bit program (written in C/C++) from my 16-bit bootloader.

  • identify the input that is multiple of 11 and odd or even java

    - by Bolor Ch
    i am trying to write code to determine the nature of input using if statement only. The nature of input could be following: a multiple of 11 even or odd. For the code below, when I enter my input, it does not display the result as "input:NOT:ODD". Also how can I check multiple conditions with if statement? (else is not considered) import java.util.Scanner; public class test { public static void main( String args[] ) { Scanner input = new Scanner( System.in ); int x; int EO; int Mult; System.out.print ( "Enter value: " ); x = input.nextInt(); EO = x % 2; Mult = x % 11; if (EO > 0 && Mult > 0) { System.out.printf ("%d:NOT:ODD"); } } }

  • How to use pointer from COM object on C#?

    - by Jaeh
    All. I'm trying to use my old dll file on .net project. So I converted this unmanaged COM object to managed one by using [tlbimp.exe] util from Windows SDK. However, one method returns a Object as a return value, but whenever I try to use it, my program generates an error. The weird thing is below: //Object[] item = s.GetObjects(); //this generates an type error Object item = s.GetObjects(); //this works okay System.WriteLine(items); //prints System.Object[] rather than System.Object. It seems like it returns a pointer which contains an object array. Isn't it ? Please anyone tell me how to handle this, and is there any documentation for this issue ?

  • What is the absolute fastest way to implement a concurrent queue with ONLY one consumer and one producer?

    - by JohnPristine
    java.util.concurrent.ConcurrentLinkedQueue comes to mind, but is it really optimum for this two-thread scenario? I am looking for the minimum latency possible on both sides (producer and consumer). If the queue is empty you can immediately return null AND if the queue is full you can immediately discard the entry you are offering. Does ConcurrentLinkedQueue use super fast and light locks (AtomicBoolean) ? Has anyone benchmarked ConcurrentLinkedQueue or knows about the ultimate fastest way of doing that? Additional Details: I imagine the queue should be a fair one, meaning the consumer should not make the consumer wait any longer than it needs (by front-running it) and vice-versa.

  • grailsApplication not getting injected in a service , Grails 2.1.0

    - by vijay tyagi
    I have service in which i am accessing few configuration properties from grailsApplication I am injecting it like this class MyWebService{ def grailsApplication WebService webService = new WebService() def getProxy(url, flag){ return webService.getClient(url) } def getResponse(){ def proxy = getProxy(grailsApplication.config.grails.wsdlURL, true) def response = proxy.getItem(ItemType) return response } } When i call getProxy() method, i see this in tomcat logs No signature of method: org.example.MyWebService.getProxy() is applicable for argument types: (groovy.util.ConfigObject, java.lang.Boolean) values: [[:], true] Possible solutions: getProxy(), getProxy(java.lang.String, boolean), setProxy(java.lang.Object) which means grailsApplication is not getting injected into the service, is there any alternate way to access configuration object ? according to burtbeckwith's post configurationholder has been deprecated, can't think of anything else. Interestingly the very same service works fine in my local IDE(GGTS 3.1.0), that means locally grailsApplication is getting injected, but when i create a war to deploy to a standalone tomcat, it stops getting injected.

  • How do I make "simple" throughput j2ee-filter?

    - by Tommy
    I'm looking to create a filter that can give me two things: number of request pr minute, and average responsetime pr minute. I already got the individual readings, I'm just not sure how to add them up. My filter captures every request, and it records the time each request takes: public void doFilter(ServletRequest request, ...() { long start = System.currentTimeMillis(); chain.doFilter(request, response); long stop = System.currentTimeMillis(); String time = Util.getTimeDifferenceInSec(start, stop); } This information will be used to create some pretty Google Chart charts. I don't want to store the data in any database. Just a way to get current numbers out when requested As this is a high volume application; low overhead is essential. I'm assuming my applicationserver doesn't provide this information.

  • Mercurial "server"

    - by user85116
    I've been using mercurial for a little while, but mainly for my own usage. Now though, I have a project I'm working on where two of us are building the same project, and we will probably be modifiying each other's files. I would like to setup a mercurial repo on a server, make that repo the "server", so my changes and the other editor's changes both push to that server (so basically the subversion / cvs model); I like mercurial though, and don't want to switch to something like subversion. Here in my own network, everything is done on linux, and my "server" has openssh installed. So pushing my changes (I work on multiple computers) from one computer to the server is just a matter of "hg push"; the protocol used is ssh for transfering the changes. The problem is that I use linux, the server will be windows (so no openssh, right?) and the other editor will be using windows too. As far as I know, the best way of working in mercurial in these types of setups is for the repo to pull changes from the source, rather then the source pushing to the "server". I'm behind several firewall's (not entirely my network) and my computer won't be visible from the server, and I'm assuming the other editor will be behind a firewall too (so we can't just start up the local mercurial http server and get the "server" computer to pull from that). What's the best way for both editors to get our changes to the server repo? (I should add that the server is a server on the internet, so just as visible as something like google.com. It's a hosted windows server, but I would probably have permission to install software if needed for this)

  • How to extend the list of available Java Locales

    - by alfonx
    I am looking for a way to add more Locales to the Locales available in Java 1.6. But the Locales I want to create do not have ISO-3166 country codes, nor ISO-639 language codes. Is there any way to do this anyways? The Locales I want to add only differ in the language names, but the smaller an ethnic group is, the more picky they get about their identity ;-) So I thought about extending an existing Locale, something like UserDefinedLocale extends Locale { UserDefinedLocale (Locale parentLocale) {...} } but java.util.Locale is final, which makes it especially hard to hack something around... So, is the idea that the list of Java Locales is exhaustive? Am I the first to miss some more Locales?
