java剪刀石头布游戏代码

在Java中实现剪刀、石头、布游戏的基本代码可能会涉及到用户输入判断以及随机选择算法。这里是一个简单的示例：

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

public class RockPaperScissors {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Random random = new Random();

        System.out.println("欢迎来到剪刀、石头、布游戏！请输入你的选择（1.剪刀，2.石头，3.布）:");
        
        int playerChoice = scanner.nextInt();
        scanner.nextLine(); // 移除换行符

        int computerChoice = random.nextInt(3) + 1; // 计算机随机选择，范围1到3
        
        System.out.println("你选择了: " + getPlayerOption(playerChoice));
        System.out.println("电脑选择了: " + getComputerOption(computerChoice));

        if (compareChoices(playerChoice, computerChoice)) {
            System.out.println("你赢了！");
        } else if (computerChoice == playerChoice) {
            System.out.println("平局！");
        } else {
            System.out.println("你输了！");
        }
    }

    private static String getPlayerOption(int choice) {
        switch (choice) {
            case 1:
                return "剪刀";
            case 2:
                return "石头";
            case 3:
                return "布";
            default:
                return "无效的选择";
        }
    }

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

    private static boolean compareChoices(int player, int computer) {
        if ((player == 1 && computer == 3) || (player == 2 && computer == 1) || (player == 3 && computer == 2)) {
            return true;
        } else {
            return false;
        }
    }
}

在这个代码中，玩家通过输入选择，计算机随机选择，然后比较两者的结果。你可以运行这个程序并尝试不同的策略。
