Helper Functions #2: "has"

In the spirit of trying to make everyone (including myself) a better programmer, I'm gonna post some helper functions that I find myself using over and over to save time, screen space, and complexity.

Here's the second one: has

Code:

private boolean has(String[] args, int index, String s) { if (args.length >= index + 1) return args[index].equalsIgnoreCase(s); return false; }

With this you don't have to worry about the length of your args. You can just check it.
For example:
if (has(args, 0, "test")) player.sendMessage("Parameter one was 'test'!");
if (has(args, 1, "delete")) player.sendMessage("Parameter two was 'delete'!");
