用Java编写猜数字游戏

在Java中，我们可以编写一个简单的猜数字游戏，通常游戏规则会有一个随机数生成器，然后让用户猜测这个数，直到猜对为止。以下是基本的游戏实现步骤：

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

public class GuessNumberGame {
    private static final int MIN_NUMBER = 1;
    private static final int MAX_NUMBER = 100;
    private int secretNumber;
    private Scanner scanner;

    public GuessNumberGame() {
        generateRandomNumber();
    }

    private void generateRandomNumber() {
        Random random = new Random();
        secretNumber = random.nextInt(MAX_NUMBER - MIN_NUMBER + 1) + MIN_NUMBER;
    }

    public boolean isCorrectGuess(int guess) {
        if (guess == secretNumber) {
            System.out.println("恭喜你，猜对了！");
            return true;
        } else if (guess < secretNumber) {
            System.out.println("猜小了，再试一次。");
        } else {
            System.out.println("猜大了，再试一次。");
        }
        return false;
    }

    public void startGame() {
        scanner = new Scanner(System.in);
        while (true) {
            System.out.print("请输入你猜的数字：");
            int userGuess = scanner.nextInt();
            if (isCorrectGuess(userGuess)) {
                break;
            }
        }
    }

    public static void main(String[] args) {
        GuessNumberGame game = new GuessNumberGame();
        game.startGame();
    }
}
