My apologies as I'm very much a "Java noob." Anyways, I think I've dumbed this problem down sufficiently to ask in a way that is straight-forward and will get me the answer I want. Let's say I have two files, both in my home directory, as follows: Test.java: class Test { public static void main(String args[]) { Test2.te...

From this question I learned Double.NaN is not equal to itself. I was verifying this for myself and noticed this is not the case if you wrap Double.NaN in a Double instance. For example: public class DoubleNaNTest { public static void main(String[] args) { double primitive = Double.NaN; Double object = new Double(pr...
I want to display a list of all the users in my site but I only want to display 10 people per age. I don't know how exactly to do this.

I want t...

I have a class (RInterfaceHL) that calls another class (JRIEngine) which provides native methods on a single-threaded application. Therefore I only want to have a single instance of my class (RInterfaceHL) per JVM. I can use the singleton pattern with static initialization to ensure only a single instantiation of RInterfaceHL, but RInt...
I'm using the built-in Java XML Transformer to serialize an XML document into text. I'm having a problem however when I am outputting in HTML mode. Whenever I insert a head element the built-in transformer decides to insert a META tag with content-type data. I don't want this tag inside my data and I can't seem to find an output paramet...

Although I have tagged this as a java/spring question it can be easily asked of any mvc framework with stateless controllers. I know rails uses simple stateless controllers for instance so perhaps you guys know how to best solve this problem.

I thought that something like this might work: if (myObject.getClass().isInstance(B.class)) { // do something for B } else (myObject.getClass().isIns...
I have been refactoring throwaway code which I wrote some years ago in a FORTRAN-like style. Most of the code is now much more organized and readable. However the heart of the algorithm (which is performance-critical) uses 1- and 2-dimensional Java arrays and is typified by: for (int j = 1; j < len[1]+1; j++) { int jj = (con...
