Java用循环语句实现石头剪刀布

好的，以下是Java实现石头剪刀布的代码：

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

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

        while (true) {
            System.out.println("请输入你的选项：1.石头 2.剪刀 3.布");
            int userOption = input.nextInt();
            int computerOption = random.nextInt(3) + 1;

            System.out.println("你出了：" + options[userOption - 1]);
            System.out.println("电脑出了：" + options[computerOption - 1]);

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

            System.out.println("是否继续？1.继续 2.退出");
            int continueOption = input.nextInt();
            if (continueOption != 1) {
                break;
            }
        }
    }
}

运行程序后，输入对应的数字即可进行石头剪刀布游戏，输入2退出游戏。
