用java实现猜拳游戏

好的，以下是用Java实现的猜拳游戏示例代码：

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

public class RockPaperScissors {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        Random random = new Random();
        String[] options = {"石头", "剪刀", "布"};
        int computerScore = 0;
        int playerScore = 0;

        System.out.println("欢迎来到猜拳游戏！");

        while (true) {
            System.out.println("\n请选择您要出的手势：");
            System.out.println("1. 石头");
            System.out.println("2. 剪刀");
            System.out.println("3. 布");
            System.out.print("请输入数字选择手势（输入 0 结束游戏）：");

            int playerChoice = input.nextInt();
            if (playerChoice == 0) {
                break;
            }

            if (playerChoice < 1 || playerChoice > 3) {
                System.out.println("输入无效，请重新输入！");
                continue;
            }

            int computerChoice = random.nextInt(3) + 1;
            System.out.println("电脑出了：" + options[computerChoice - 1]);

            if (playerChoice == computerChoice) {
                System.out.println("平局！");
            } else if ((playerChoice == 1 && computerChoice == 2) || (playerChoice == 2 && computerChoice == 3) || (playerChoice == 3 && computerChoice == 1)) {
                System.out.println("恭喜您获胜！");
                playerScore++;
            } else {
                System.out.println("很遗憾，您输了！");
                computerScore++;
            }

            System.out.println("您的得分：" + playerScore);
            System.out.println("电脑的得分：" + computerScore);
        }

        System.out.println("游戏结束，谢谢您的参与！");
    }
}

这个程序使用了while循环，玩家可以选择石头、剪刀或布来进行游戏，电脑会随机出手势。程序会根据出拳的结果判断胜负，并输出得分。当玩家输入 0 时，程序会结束游戏。
