• Select SWT Library depending on OS

  - by phineas

  How do I ensure when I distribute a JAR-file that the proper SWT-library (either the windows, the linux or mac version) is loaded an ready to use? It would be very helpful because then you can do one export and your application can run on any platform like Swing apps usually do. Thanks a lot

• Browser compatibility; Before or after uploading website to server?

  - by Camran

  I am on the stage where I need to make my website cross-browser compatible. I need tips on how to get started. I have developed my website on firefox, so it works great with firefox. I guess I have to download a couple of versions of all major browsers now, right? Then just test each browser one by one? Should I do this before uploading the entire website onto a server or afterwards? All tips and SW which makes this easier is appreciated. BTW, it is a classifieds website using MySql, Solr, PHP, js etc... Thanks

• Hibernate 1:M relationship ,row order, constant values table and concurrency

  - by EugeneP

  table A and B need to have 1:M relationship a and b are added during application runtime, so A created, then say 4 B's created. Each B instance has to come in order, so that I could later extract them in the same order as I added them. The app will be a web-app running on Tomcat, so 10 instances may work simultaneously. So my question are: 1) How to preserve inserting order, so that I could extract B instances that A references in the same order as I persisted them. That's tricky, because we add to a Collection and then it gets saved (am I right?). So, it depends on how Hibernate saves it, what if it changes the order in what we added instances? I've seen something like LIST instead of SET when describing relationships, is that what I need? 2) How to add a 3-rd column to B so that I could differentiate the instances, something like SEX(M,F,U) in B table. Do I need a special table, or there's and easy way to describe constants in Hibernate. What do you recommend? 3) Talking about concurrency, what methods do you recommend to use? There should be no collisions in the db and as you see, there might easily be some if rows are not inserted (PK added) right where it is invoked without delays ?

• Junit | How to test parameters in a method

  - by MMRUser

  How do I test parameters inside a method itself. For example class TestClass { public void paraMethod(String para1, String para2) { String testPara1 = para1; String testPara2 = para2; } } class TestingClass { @Test public void testParaMethod () throws Exception { String myPara1 = "MyPara1"; String myPara2 = "MyPara2"; new TestClass().paraMethod(myPara1, myPara2); } } Ok, so is it possible to test if the testPara1 and testPara2 are properly set to the values that I have passed? Thanks.

• Color getAlpha() not working as intended

  - by Arvy

  I was making a program where I load an image and after that I do something with opaque pixels. Transparent pixels showed up as black pixels, but after some time I found the cause: Color c = new Color (input.getRGB(x, y)); Works-> if ((input.getRGB(x, y) & 0xFF000000) != 0x00000000) { do_smth();} Returns true at all times-> if (c.getAlpha() != 0) { do_smth(); } So why it does not work?

• Include multiple jars with classpathentry

  - by ripper234

  I have an eclipse's .classpath file that looks like this: <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src"/> <classpathentry kind="src" path="test"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="output" path="bin"/> <classpathentry kind="lib" path="/libraries/jee/servlet-api.jar"/> <classpathentry kind="lib" path="/libraries/junit/junit-4.6.jar"/> <classpathentry kind="lib" path="/libraries/log4j/log4j-1.2.15.jar"/> </classpath> I'd like to add a whole directory of jars to the classpath - I like eclipse (or more precisely, our ant-based build process that uses .classpath format) to know several jars that reside in a single directory, without specifying them directly. How can I do that?

• Android - How can I access a View object instantiated in onCreate in onResume?

  - by Chris

  In my onCreate() method, I'm instantiating an ImageButton View: public void onCreate(Bundle savedInstanceState) { Log.d(AntengoApplication.LOG_TAG, "BrowsePicture onCreate"); super.onCreate(savedInstanceState); setContentView(R.layout.layout_post); final ImageButton ib = (ImageButton) findViewById(R.id.post_image); ... In onResume, I want to be able to change the properties of the ImageButton with something like: @Override protected void onResume() { super.onResume(); ib.setImageURI(selectedImageUri); } //END onResume But onResume doesn't have access to the ib ImageButton object. If this were a variable, I'd simple make it a class variable, but Android does not allow you to define View object in the class. Any suggestions on how to do this?

• How is this function being made use of?

  - by Kay

  Hello all, I am just studying a few classes given to me by my lecturer and I can't understand how the function heapRebuild is being made used of! It doesn't change any global variables and it doesn't print out anything ad it doesn't return anything - so should this even work? It shouldn't, should it? If you were told to make use of heapRebuild to make a new function removeMac would you edit heapRebuild? public class MaxHeap<T extends Comparable<T>> implements Heap<T>{ private T[] heap; private int lastIndex; public T removeMax(){ T rootItem = heap[0]; heap[0] = heap[lastIndex-1]; lastIndex--; heapRebuild(heap, 0, lastIndex); return rootItem; } protected void heapRebuild(T[ ] items, int root, int size){ int child = 2*root+1; if( child < size){ int rightChild = child+1; if ((rightChild < size) && (items[rightChild].compareTo(items[child]) > 0)){ child = rightChild; } if (items[root].compareTo(items[child]) < 0){ T temp = items[root]; items[root] = items[child]; items[child] = temp; heapRebuild(items, child, size);} } } }

• Which way of declaring a variable is fastest?

  - by ADB

  For a variable used in a function that is called very often and for implementation in J2ME on a blackberry (if that changed something, can you explain)? class X { int i; public void someFunc(int j) { i = 0; while( i < j ){ [...] i++; } } } or class X { static int i; public void someFunc(int j) { i = 0; while( i < j ){ [...] i++; } } } or class X { public void someFunc(int j) { int i = 0; while( i < j ){ [...] i++; } } } I know there is a difference how a static versus non-static class variable is accessed, but I don't know it would affect the speed. I also remember reading somewhere that in-function variables may be accessed faster, but I don't know why and where I read that. Background on the question: some painting function in games are called excessively often and even small difference in access time can affect the overall performance when a variable is used in a largish loop.

• Hibernate Performance Best Practice?

  - by user829237

  Im writing a Web application using Hibernate 3. So, after a while i noticed that something was slow. So i tested hibernate profiler and found that hibernate will make unreasonably many db-calls for simple operation. The reason is ofcourse that i load an Object (this object has several "parents") and these "parents" have other "parents". So basicly hibernate loads them all, even though i just need the basic object. Ok, so i looked into lazy-loading. Which lead me into the Lazyloading-exception, because i have a MVC webapp. So now i'm a bit confused as to what is my best approach to this. Basicly all I need is to update a single field on an object. I already have the object-key. Should I: 1. Dig into Lazy-loading. And then rewrite my app for a open-session-view? 2. Dig into lazy-loading. And then rewrite my dao's to be more specific. E.g. writing DAO-methods that will return objects instanciated with only whats necessary for each use-case? Could be a lot of extra methods... 3. Scratch hibernate and do it myself? 4. Cant really think of other solutions right now. Any suggestions? What is the best practice?

• How do I setup Eclipse to stop on the line an exception occured?

  - by Chris Persichetti

  Hi, How can I setup Eclipse to stop at the point an exception occurred. I have an Eclipse breakpoint setup to break on an exception. In the code example below, the problem I'm having is Eclipse tries to open the Integer source code. Is there any way to just have debugger break at the point shown in my code example? If I move down the stack trace, I will get to this line, it'd be nice if there's a way to do this without the "Source not found" window coming up. This can be done in Visual Studio, so it's driving me crazy not being able to find a way to do this in Eclipse. package com.test; public class QuickTest { public static void main(String[] args) { try { test(); } catch(NumberFormatException e) { System.out.println(e.getMessage()); } } private static void test() { String str = "notAnumber"; Integer.parseInt(str);//<----I want debugger to stop here } }

• 'For' Loop Within a 'For' Loop and Then Another?

  - by BenjaminFranklin

  This has confused me quite a bit, but it's also really interesting! I want to loop through a grid of 9 elements in an array, multiply them all by 1/9. Then, I want to find the sum of those 9 elements and replace each individual element's with the value calculated as the sum. After I've done this, I want to move on to the next nine elements. To clarify, I want all 9 elements to be changed to myVal, in the code below. So far I've got the loop within a loop bit, but I don't know how to then go back and replace each of the values with the sum of all of them combined. Here's my code:- previousx = 0; previousy= 0; for (int x = previousx; x < previousx+4; x++) { for(int y = previousy; y < previousy+4; y++) { y = y*(1/9); yVal += y; } } Any advice would, of course, be greatly appreciated.

• Variable from block is put into a calculation but throws off wrong reading

  - by user2926620

  I am having troubles with trying to retrieve a double variable that is already established outside the block and called inside but I want to return the value of the same variable so that I can apply it to a calculation. the variable that I want returned is: double quarter = 0; but when I plug it into quarter in my first else/if statement, it plugs in 0 and not the value in my switch block. What can I do to retrieve the value? double quarter = 0; //Date entry will be calculated by how much KW user enters switch (input) { case "2/15/13": quarter = kwUsed * 0.10; break; case "4/15/13": quarter = kwUsed * 0.12; break; case "8/15/13": quarter = kwUsed * 0.15; break; case "11/15/13": quarter = kwUsed * 0.15; break; default: System.out.println("Invalid date"); } //Declaring variables for calculations double base = 0; double over = 0; double excess = 0; double math1 = 0; double math2 = 0; //KW Calculations if (kwUsed <= 350) { base = quarter; }else if (kwUsed <= 500) { math1 = ((kwUsed - 350) * quarter); base = ((kwUsed * quarter) - math1); over = ((math1 * 0.1) + math1); }else if (kwUsed > 500) { math2 = ((kwUsed - 350) * 0.1); base = ((kwUsed * 0.1) - math2); math2 = ((kwUsed -350) - 50); over = ((math2 * 0.1) + (15 * 0.1)); double math3 =((kwUsed - 500) * 0.1); excess = ((math3 * 0.25) + math3); } Edited to clarify question.

  Over and over again I notive myself getting a list from hibernate, and the first thing next is put it in an idmap like: List<House> entities = s.createCriteria(House.class).list(); Map<String,House> entitymap = new HashMap<String,House>(); for(TA_entity e:entities){ entitymap.put(e.getId(), e); } Is there a way to get this directly out of hibenerate? afterall Hibernate is familiar with the id.
