java猜数字1-100游戏编程，添加初级、中级、高级三个选择

在Java中，你可以创建一个猜数字游戏，让用户从1到100之间猜测，同时提供初级、中级、高级三个难度等级。以下是基本的游戏框架：

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

public class GuessNumberGame {
    enum DifficultyLevel {
        EASY(1), MEDIUM(50), HARD(100);
        private final int rangeStart;

        DifficultyLevel(int rangeStart) {
            this.rangeStart = rangeStart;
        }

        int getRangeStart() {
            return rangeStart;
        }
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        DifficultyLevel level;
        int randomNumber, attempts = 0;

        // 获取用户选择的难度级别
        System.out.println("选择难度等级:");
        System.out.println("1. 初级 (1-50)");
        System.out.println("2. 中级 (51-100)");
        System.out.println("3. 高级 (1-100)");
        level = chooseDifficulty(scanner);

        // 生成随机数
        randomNumber = level.getRangeStart() + new Random().nextInt(level.getRangeEnd() - level.getRangeStart());

        // 游戏循环
        while (true) {
            System.out.println("你在 " + level.getDescription() + " 难度下，有猜测机会。");
            System.out.print("请输入你的猜测数字 (1-" + level.getRangeEnd() + "): ");
            int guess = scanner.nextInt();

            if (guess == randomNumber) {
                System.out.println("恭喜，你猜对了！你一共尝试了 " + ++attempts + " 次。");
                break;
            } else if (guess < randomNumber) {
                System.out.println("太小了，再试一次吧！");
            } else {
                System.out.println("太大了，再试试。");
            }
        }

        scanner.close();
    }

    private static DifficultyLevel chooseDifficulty(Scanner scanner) {
        System.out.print("你的选择是: ");
        int input = scanner.nextInt();
        switch (input) {
            case 1:
                return DifficultyLevel.EASY;
            case 2:
                return DifficultyLevel.MEDIUM;
            case 3:
                return DifficultyLevel.HARD;
            default:
                System.out.println("无效的选择，请重新输入！");
                return chooseDifficulty(scanner);
        }
    }

    // 描述等级的辅助方法
    private static String getDescription(DifficultyLevel level) {
        switch (level) {
            case EASY:
                return "1-50";
            case MEDIUM:
                return "51-100";
            case HARD:
                return "1-100";
        }
    }
}

在这个游戏中，玩家可以选择不同难度，然后电脑随机生成一个范围内的数字，直到玩家猜对为止。
