  • MyApp create instances of both MyScreen and NextScreen, allowing the user to navigate between screens. This is by immediately pushing Myscreen and then adding a changeListener to the button on MyScreen to navigate to NextScreen
  • The NextScreen Class will create setup the tic tac toe board and request user input for their moves. It does not allow invalid input, and once a piece has been placed, the user cannot place another piece on that square.
  • After a player makes a move, the next player is requested to place their move and so on until a winner is determined, it is a tie game, or the reset button has been pressed.
