Java Programming Tips and Tricks

This document contains miscellaneous "magic formulas" and other useful stuff I've had to invent because I couldn't find it already on the web (or got tired of hunting for after the fifteenth attempt).

    Color c = Color.blue;
    String s = Integer.toHexString(c.getRGB());
    s = s.substring(s.length() - 6);
