How does the Java 'for each' loop work?

With 5 cases, the d...
How to automatically generate N “distinct” colors?
I wrote the two methods below to automatically select N distinct colors. It works by defining a piecewise linear function on the RGB cube. The benefit of this is you can also get a progressive scale if that's what you want, but when N gets large the colors can start to look similar. I can also imagi...
