  1. Fun little optimization

    Disclaimer: While optimizations can be fun and addictive, determine if your particular application needs any before attempting to optimize it.

    I've always wondered if the Java compiler was capable of performing certain loop optimizations. So for fun, I picked a two of them (a simple permutation and loop unrolling) and tested them out.

    public class Test
    	public static void main(String[] args)
    		final int DIM = 0x2000;
