Need Help with ArrayList sorting

[ggatwork]

Okay, I'm doing a program where a menu pops up and it deals with the roster of a basketball team. You can add, edit, delete, and view the players. All of this is working but my problem is with sorting the players. I'm using an ArrayList (ArrayList contains each player's name, number, height, weight, etc.)object for the roster. I've been trying to use Collections.sort but it seems I'm doing something wrong. Anyone help would be greatly appreciated.

Here's the code if you need to see it:(Code referring to this problem is bold)
