Questions about my Color Array

I didn’t bother warning about that b/c the colors[] array already had 3 elements in it. BtW, here’s an even shorter version w/ just while () instead of do // while (): void pick() { int newIndex; while ((newIndex = (int) random(colors.length)) == index); index = newIndex; } Nonetheless, a custom shuffle() approach (from my previous posted link) is much more commendable: @ SafeVarargs final int[] shuffle(final int... arr) { if (arr == null) return null;…
