Stuck on Java Project

Question

/**so here is my project. if you run the gui you can see sorta what i am trying to do. Im trying to get have data input for the three categories to find averages for the players and keep them in the memory for a short time so you can flip through the seven players. I understand it is a pain to go through the whole project so sorry about it. I just really need some help. I cant figure out how to get it to get the output for the aces winners and errors and attach them to the player. I think it is something with the arrays but i dont know what to do with it. here is the first class. The second class is below it.**/
