java1.用程序模拟石头剪刀布，电脑随机出拳，用户通过输入出拳，三局两胜。控制台输出“xx赢了”

可以使用Java编写一个程序来模拟石头剪刀布游戏，以下是一个简单的实现示例：

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

public class RockPaperScissors {
    public static void main(String[] args) {
        int userScore = 0;
        int computerScore = 0;
        int rounds = 0;
        
        while (userScore < 2 && computerScore < 2) {
            System.out.println("请输入你的选择（1-石头，2-剪刀，3-布）：");
            Scanner scanner = new Scanner(System.in);
            int userChoice = scanner.nextInt();
            
            int computerChoice = generateComputerChoice();
            
            System.out.println("电脑选择了：" + getChoiceName(computerChoice));
            
            int result = compareChoices(userChoice, computerChoice);
            
            if (result == 1) {
                userScore++;
                System.out.println("你赢了这局！");
            } else if (result == -1) {
                computerScore++;
                System.out.println("电脑赢了这局！");
            } else {
                System.out.println("这局平局！");
            }
            
            rounds++;
        }
        
        if (userScore > computerScore) {
            System.out.println("你赢了比赛！");
        } else {
            System.out.println("电脑赢了比赛！");
        }
    }
    
    private static int generateComputerChoice() {
        Random random = new Random();
        return random.nextInt(3) + 1;
    }
    
    private static String getChoiceName(int choice) {
        if (choice == 1) {
            return "石头";
        } else if (choice == 2) {
            return "剪刀";
        } else {
            return "布";
        }
    }
    
    private static int compareChoices(int userChoice, int computerChoice) {
        if (userChoice == computerChoice) {
            return 0;
        } else if ((userChoice == 1 && computerChoice == 2) ||
                   (userChoice == 2 && computerChoice == 3) ||
                   (userChoice == 3 && computerChoice == 1)) {
            return 1;
        } else {
            return -1;
        }
    }
}
