java:石头剪刀布

以下是使用Java程序代码完成石头剪刀布游戏的示例：

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

public class RockPaperScissors {
    public static void main(String[] args) {
        String[] choices = {"石头", "剪刀", "布"};

        Scanner scanner = new Scanner(System.in);
        Random random = new Random();

        System.out.println("欢迎来到石头剪刀布游戏！请选择：");
        System.out.println("1. 石头");
        System.out.println("2. 剪刀");
        System.out.println("3. 布");

        int playerChoice = scanner.nextInt();
        int computerChoice = random.nextInt(3) + 1;

        System.out.println("你选择了：" + choices[playerChoice - 1]);
        System.out.println("电脑选择了：" + choices[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("你赢了！");
        } else {
            System.out.println("你输了！");
        }
    }
}
