My assignment:
develop a limited application to track the statistics of sports players. For each player, track first and last name, points scored, assists made, and penalty rate. Design and implement an object capable of recording this info. Implement this object as Player. Must allow user to enter new player info for any number of players, store all the info for each player, and allow certain queries to be made on player stats. Application must prompt user to perform operations (Add, Remove, Show, Save, Quit).
I have the most of the program completed. I have an issue with showing the players which basically prints the entire arrayList toString in a formatted manner. It looks like it should work but then again, it's a bit simplistic so why would it?
The other problem I am having is removing a player from the list. I know that arrayList.remove() should be a part of the solution but I don't know how to to find the player by the first and last name stored in each object.
If you need me to post my code for my player object, let me know.
Also if any of this looks like it sucks for whatever reason, please let me know. Although, improvements come after functionality.
This is homework. Please do not write my code for me. Any help otherwise would be greatly appreciated. If I find the answer before somebody posts I will update with my progress.
Here is my code:

// adds a new player object to playerList
