Question
Please help! I need to write a Java program that displays a 3 x 3 grid of buttons that are initially numbered 1 through 9, as shown below. When the user presses a button, use the setText method to change the button’s label to either “x” or “o” (the program should alternate between them). This is essentially a lame version of tic tac toe.Thank you!!!
