写一个java猜拳游戏

好的，下面是一个简单的 Java 猜拳游戏示例：

import java.util.Random;
import java.util.Scanner;

public class RockPaperScissors {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Random random = new Random();
        String[] options = {"rock", "paper", "scissors"};

        while (true) {
            System.out.print("Please choose rock, paper, or scissors (or quit to exit): ");
            String playerChoice = scanner.nextLine().toLowerCase();

            if (playerChoice.equals("quit")) {
                break;
            }

            int computerChoiceIndex = random.nextInt(3);
            String computerChoice = options[computerChoiceIndex];

            System.out.println("Computer chooses " + computerChoice);

            if (playerChoice.equals(computerChoice)) {
                System.out.println("It's a tie!");
            } else if ((playerChoice.equals("rock") && computerChoice.equals("scissors")) ||
                    (playerChoice.equals("paper") && computerChoice.equals("rock")) ||
                    (playerChoice.equals("scissors") && computerChoice.equals("paper"))) {
                System.out.println("You win!");
            } else {
                System.out.println("Computer wins!");
            }
        }
    }
}

运行后，你可以通过输入 rock、paper、scissors 进行游戏。当你输入 quit 时，游戏结束。每次游戏结束后，程序会显示出你和电脑的选择以及胜负结果。
