40行java小游戏源代码

以下是一个简单的 Java 小游戏——“猜数字”（Guess Number）的代码示例，共计 40 行：

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

public class GuessNumber {
    public static void main(String[] args) {
        Random rand = new Random();
        int numberToGuess = rand.nextInt(100) + 1;
        int numberOfTries = 0;
        Scanner input = new Scanner(System.in);
        int guess;
        boolean win = false;

        while (win == false) {
            System.out.print("Guess a number between 1 and 100: ");
            guess = input.nextInt();
            numberOfTries++;

            if (guess == numberToGuess) {
                win = true;
            } else if (guess < numberToGuess) {
                System.out.println("Your guess is too low.");
            } else if (guess > numberToGuess) {
                System.out.println("Your guess is too high.");
            }
        }

        System.out.println("Congratulations! You win!");
        System.out.println("The number was " + numberToGuess);
        System.out.println("It took you " + numberOfTries + " tries to guess the number.");
    }
}

这个游戏生成一个 1 到 100 之间的随机整数，玩家需要猜测这个数字。程序会提示玩家输入猜测的数字，并根据玩家的输入给出相应的提示（猜测的数字太高或太低）。如果玩家猜对了数字，游戏结束并输出猜测次数。
