My intention was to create a JForm in which to play the cat, every time you save that JForm in a list, at the end of a certain number of games won (4 in this code) show the windows that you save in the list where you can see how the game was won and if it was with X or O.
The problem is that if it does what I want, but I can not understand what happens internally in the object and the reference to it. In the checkForWin() method I pass to the list the reference to the object by this and it works correctly, unlike when instead of this I pass the reference to otro .
