How Would I Draw on Second Board For Tic Tac Toe
I am trying to create a 'Shadow TicTacToe' game for a final project for an Intro to Programming class.
The way this game is supposed to work is that a user clicks a cell in the first board and an X or O will be drawn. That X will also be drawn in the same cell, but different spot on the second game board. By different spot I mean if cell(2,3) is on the center tile on the first game board that same cell would be on the top right tile(or on some other tile) on the second game board.
I have created the first and second board, each in a JPanel. I am just having trouble creating a way for whatever token is in one cell on the first game board to be in the same cell on the second game board. I created 2 cells, one for each game board, let me know if that is just complicating things or I really do need 2 cells. I am just stuck on this one part of the project and any help is appreciated.
Description of final project for clarification:
Code(so far, still have a few things to do):

Solution
You need to add an index to each Cell and that index will map your cells from board 1 and board 2. You will draw the token, in the second board, on the Cell that has the same index as the Cell on the first Board. Just as you see in your image. Because if you go through the coordinates system you loose track and the boards will be equal.
