用java实现剪刀石头布

好的，以下是Java实现剪刀石头布的代码：

import java.util.Scanner;

public class RockPaperScissors {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int playerChoice, computerChoice;

        while (true) {
            System.out.print("请选择（1：剪刀，2：石头，3：布，0：结束游戏）：");
            playerChoice = sc.nextInt();
            if (playerChoice == 0) {
                System.out.println("游戏结束！");
                break;
            }
            computerChoice = (int) (Math.random() * 3) + 1;
            System.out.println("电脑出拳：" + getChoice(computerChoice));
            if (playerChoice == computerChoice) {
                System.out.println("平局！");
            } else if ((playerChoice == 1 && computerChoice == 3)
                    || (playerChoice == 2 && computerChoice == 1)
                    || (playerChoice == 3 && computerChoice == 2)) {
                System.out.println("你赢了！");
            } else {
                System.out.println("你输了！");
            }
        }
        sc.close();
    }

    private static String getChoice(int choice) {
        switch (choice) {
            case 1:
                return "剪刀";
            case 2:
                return "石头";
            case 3:
                return "布";
            default:
                return "";
        }
    }
}

运行代码后，会提示输入选择，输入1、2、3分别代表剪刀、石头、布，输入0则结束游戏。计算机会随机出拳，并判断胜负。
