使用java编写程序实现“剪刀石头布”的游戏，相信大家都不陌生，本案例要求编写一个剪刀石头布游戏的程序。程序启动后会随机生成1~3的随机数，分别代表剪刀、石头和布，玩家通过键盘输入剪刀、石头和布与电脑进行5轮的游戏，赢的次数多的一方为赢家。若五局皆为平局，则最终结果判为平局。

为了编写一个简单的剪刀石头布游戏，你可以按照以下步骤进行：

首先，创建一个GameRound类来表示一轮游戏：

import java.util.Random;

public class GameRound {
    private enum Choice {SCISSORS, STONE, PAPER}

    public Choice getUserChoice() {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请选择剪刀（1）、石头（2）或布（3）:");
        int input = scanner.nextInt();
        return input == 1 ? Choice.SCISSORS : input == 2 ? Choice.STONE : Choice.PAPER;
    }

    public Choice getComputerChoice() {
        Random random = new Random();
        return Choice.values()[random.nextInt(Choice.values().length)];
    }

    public boolean isWinning(Choice user, Choice computer) {
        return (user == Choice.SCISSORS && computer != Choice.SCISSORS) ||
               (user == Choice.STONE && computer != Choice.PAPER) ||
               (user == Choice.PAPER && computer != Choice.STONE);
    }

    public int play() {
        Choice user = getUserChoice();
        Choice computer = getComputerChoice();
        System.out.printf("您出的是：%s, 电脑出了：%s\n", user, computer);
        return isWinning(user, computer) ? 1 : isWinning(computer, user) ? -1 : 0;
    }
}

接着，在主程序中设置循环来运行5轮游戏并计算总分数：

public class RockPaperScissorsGame {
    public static void main(String[] args) {
        GameRound game = new GameRound();
        int playerScore = 0;
        int computerScore = 0;
        int round = 1;

        while (round <= 5) {
            int result = game.play();
            if (result == 1) {
                playerScore++;
                System.out.println("恭喜，第" + round++ + "轮您赢了！");
            } else if (result == -1) {
                computerScore++;
                System.out.println("很遗憾，第" + round++ + "轮电脑赢了！");
            } else {
                System.out.println("平局！第" + round++ + "轮双方持平。");
            }
        }

        if (playerScore > computerScore) {
            System.out.println("恭喜，您赢得了比赛，总分：" + playerScore + "对" + computerScore);
        } else if (computerScore > playerScore) {
            System.out.println("电脑赢了比赛，总分：" + computerScore + "对" + playerScore);
        } else {
            System.out.println("游戏结束，双方打成平局，总分：" + playerScore + "对" + computerScore);
        }
    }
}

当用户运行这个程序时，他们将能够与计算机玩5轮剪刀石头布游戏，并看到每轮的结果。
