java人机猜拳代码

当然可以！以下是一个简单的Java人机猜拳代码示例：

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

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("欢迎来到猜拳游戏！请选择：");
        System.out.println("1. 石头");
        System.out.println("2. 剪刀");
        System.out.println("3. 布");

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

        System.out.println("你选择了：" + choices[userChoice - 1]);
        System.out.println("电脑选择了：" + choices[computerChoice - 1]);

        if (userChoice == computerChoice) {
            System.out.println("平局！");
        } else if ((userChoice == 1 && computerChoice == 2) ||
                (userChoice == 2 && computerChoice == 3) ||
                (userChoice == 3 && computerChoice == 1)) {
            System.out.println("你赢了！");
        } else {
            System.out.println("你输了！");
        }
    }
}

这个代码实现了一个简单的人机猜拳游戏。用户通过输入数字选择石头、剪刀或布，电脑随机生成一个选择，然后比较两者的选择来判断胜负。
