When an exception occurs in a method, the method does not exit immediately if it does not catch the...
The object ticTacToeBoard is initialized to indicate if the computer is the player 1 or player 2. Your task is to allow turns between the player and computer and to determine if a winner exists. The TicTacToeBoard class uses a Character class which is a wrapper class for char. It allows for the value null. Thus, the board values can be ‘X’,’O’ or null. Program Requirements In the TicTacToe class, set the existing Long variable named securityCode with a value...
Enhance and correct a Tic Tac Toe game. The game is intended to be played against a computer. The object TicTacToeBoard is initialized to indicate if the computer is the player 1 or player 2. Your task is to allow turns between the player and computer and to determine if a winner exists. Keyboard input implies using the Scanner object. Review Section 7.7 in the textbook. Ideally, do 1 task at a time and test the results. The tasks are...
