Rock Paper Scissors

Rock, Paper, Scissors… Swing?

My first experience with scripting a user interface involved developing a simple Rock-Paper-Scissors game using Java and Swing. In this program, the user plays a game of Rock-Paper-Scissors against the computer and features a straightforward interface with buttons for Start, Instructions, Exit, and the three game choices—Rock, Paper, and Scissors. Additionally, the user interface has a display area showing game results and messages. This program gave me hands-on experience with creating a user-friendly interface and event-driven programming.

Code Leak-oko

The project was divided into three .java files:

The game logic uses numerical values to represent game choices: 0 for Rock, 1 for Paper, and 2 for Scissors. A random number generator was then used to generate the computer’s choice based on these values, which is then compared with the player’s choice to determine the outcome of each round.

 public void playRound(int userChoice) {

        // Make the random number become the computer's choice
        computerChoice = randomNumber();

        // Convert the random number to "Rock", "Paper", or "Scissors"
        String computerChoiceString = choices[computerChoice];

        // Print computer's choice to terminal (this was used in early testing)
        System.out.println("Computer chose: " + computerChoiceString);

        // If both choices are the same, it's a tie
        if (userChoice == computerChoice){
            System.out.println("Tie");          // Print "Tie" in terminal (early testing)
            tieCounter++;                         // Increase Tie Counter
            userWins = false;                     // Change userWins bool to false
        // Else if user beats computer, user wins
        } else if ((userChoice == 0 && computerChoice == 2) ||
                    (userChoice == 1 && computerChoice == 0) ||
                    (userChoice == 2 && computerChoice ==1)) {
            System.out.println("You win!");     // Print "You win!" in terminal (early testing)
            userScore++;                          // Increase User Score
            userWins = true;                      // Change userWins bool to true
        // Else user loses
        } else {
            System.out.println("You lose");     // Print "You lose" in terminal (early testing)
            computerScore++;                      // Increase Computer Score
            userWins = false;                     // Change userWins bool to false
        }
    }
