Question
Newer to Java, don't want a complex tic-tac-toe program just an easy basic one.Design and code a swing GUI for a 2 player tic-tac-toe game on a 3x3 board. The JFrame should use a BorderLayout with a JLabel in the NORTH region to display messages and a JPanel in the CENTER region to display the board. For the board in JPanel use a grid layout manager with a 3x3 layout of JButton's in each cell to display the game board. The button label should initially be blank. When a player clicks on an empty button an X or O should be placed in the label field of the button depending on the player. Display the winner in the JLabel at the top of the window if there is one. If all 9 cells have been filled without a winner the program should indicate there was a tie.
