I'm just getting started with javafx in NetBeans, and I have it doing simple stuff (windows with buttons + the like) but would like to try something slightly more realistic. The "Swing/AWT Components" palette has a whole bunch of stuff that the "JavaFX Script Code Clips" palette does not (it has Button, CheckBox, ComboBox, ComboBoxItem,...
I've made a small RSS Reader app using Swing and Eclipse keeps telling me "The serializable class MochaRSSView does not declare a static final serialVersionUID field of type long" What is serialization and what benefits would it have? ...
I have a class, which I have simplified to this: final class Thing { private final int value; public Thing(int value) { this.value = value; } public int getValue() { return value; } @Override public String toString() { return Integer.toString(value); } } I want to sort an array of th...
Why does: public class Addition { public static void main() { int a = 0; double b = 1.0; a = a + b; System.out.println(a); } } not compile but: public class Addition { public static void main() { int a = 0; double b = 1.0; a += b; System.out.println(a); } } compiles. ...
This is just part of the code, so never mind if you can't see the arrays or anything else. The idea is that I have 5 cards and I want to determine which ones are pairs. Does anyone understand what I mean? boolean IsOnePair=true; int [] cont = new int [6]; for (int i=0;i<Game.length;i++) { cont[Game[i].getValue()] ++; } for (int i...
I have a web app that have many tables (each represents a POJO). I wrote mapping files for each class and then use Hibernate's SchemaExport to generate the tables in my database. Now I want to create 2 additional tables for each existing table that was created: User permission table - stores user permissions on the POJO specific to ea...
This is probably a really basic problem but I can't seem to find any other articles on it. Anyway, I have written a small bouncing ball program in Java to try and expand my basic skills. The program is just a simple bouncing ball that will drop and hopefully bounce for a while. The original program worked fine but now I have tried to ad...

I would like to find the window ID of my SWT program. I start up my SWT shell in the standard way. How do I then find the ID of the window that's been created? The program is executing on Fedora 10 using the Compiz-Fusion window manager (if that makes a difference). Code to help explain what I mean: public static void main(String[] ar...

I currently have a technical point of difference with an acquaintance. In a nutshell, it's the difference between these two basic styles of Java exception handling: Option 1 (mine): try { ... } catch (OneKindOfException) { ... } catch (AnotherKind) { ... } catch (AThirdKind) { ... } Option 2 (his): try { ... } catch (AppException e)...
Im mainly looking at the EntityStatics (http://www.hibernate.org/hib_docs/v3/api/org/hibernate/stat/EntityStatistics.html). I can see a lot of fetch, loads and updates and i cant find anywhere that says what the difference between them are. ...
First, some background: I will have to work on code for a JSP that will demand a lot of code fixing and testing. This JSP will receive a structure of given objects, and render it according to a couple of rules. What I would like to do, is to write a "Test Server" that would read some mock data out of a fixtures file, and mock those obj...
Is there Anyone that has experience with any open source, or relatively cheap voice recognition API for java? I'm pretty much looking for something that will turn spoken words into text. From the java speech recognition page on sun, it seems that it is something that is rather dead. My requirements is something that at the least runs on...
is this allowed in java: for(int i=0;i<5;i++){ final int myFinalVariable = i; } The keyword of my question is final. Is it allowed to do a final variable that changes with every run of the loop? I was wondering this because final says that you can't change the value of the variable (calling only myFinalVariable = i), but i'm redefin...

Hi, I have a question regarding the development of liferay portlets using the liferay plugin SDK. My question goes mainly in the setup of the development IDE. The suggested one would be to use Netbeans IDE which I also tried out, but it appears to run very slowly on my machine while Eclipse is quite performant. The setup for Netbeans ID...
How much is read from ThreadLocal variable slower than from regular field? More concretely is simple object creation faster or slower than access to ThreadLocal variable? I assume that it is fast enough so that having ThreadLocal<MessageDigest> instance is much faster then creating instance of MessageDigest every time. But does that al...
I have a text field which is bound with Integer variable, so when user enters number into this field, binding mechanism automatically converts text into Integer and sets this value into var. Problem is, since user types text into text field, that binding mechanism is converting only values, and if user types some letters into it, binding...
