Question

Using Java, write a program that allows the user to play the Rock-Paper-Scissors game against the computer through a user interface. The user will choose to throw Rock, Paper or Scissors and the computer will randomly select between the two. In the game, Rock beats Scissors, Scissors beats Paper, and Paper beats Rock. The program should then reveal the computer's choice and print a statement indicating if the user won, the computer won, or if it was a tie. Allow the user to continue playing until they choose to stop. Once they stop, print the number of user wins, losses, and ties.

Here are the two separate files that create the mainframe and the panel.

   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

   frame.getContentPane().add(new RockPaperScissorsPanel());
   frame.pack();

   frame.setVisible(true);
 }
}
