java实现的简单猜数字游戏代码

本文实例讲述了java实现的简单猜数字游戏代码。分享给大家供大家参考。

具体代码如下：

import java.util.InputMismatchException;

import java.util.Scanner;

public class Main {

        public static void main(String[] args) {

                // 产生一个随机数

                int number = (int) (Math.random() * 100) + 1;
                // 加入count

                int count = 0;
                // 在这里加入最大值，和最小值

                int max = 100;

                int min = 1;
                while (true) {

                        // 键盘录入数据

                        Scanner sc = new Scanner(System.in);

                        System.out.println("请输入你要猜的数据：(" + min + "~" + max + ")");

                        try {

                                count++;

                                int guessNumber = sc.nextInt();

                                // 判断

                                if (guessNumber > number) {

                                        max = guessNumber;

                                        System.out.println("你猜大了");

                                } else if (guessNumber < number) {

                                        min = guessNumber;

                                        System.out.println("你猜小了");

                                } else {

                                        System.out.println("恭喜你,花了" + count + "次就猜中了");

                                        // 问是否继续

                                        System.out.println("请问还要继续吗？(yes)");

                                        sc = new Scanner(System.in);

                                        String str = sc.nextLine();

                                        if ("yes".equals(str)) {

                                                // 重写赋值随机数

                                                number = (int) (Math.random() * 100) + 1;

                                                count = 0;

                                                max = 100;

                                                min = 1;

                                        } else {

                                                break;

                                        }

                                }

                        } catch (InputMismatchException e) {

                                System.out.println("你输入的数据有误");

                        }

                }

        }

}

运行结果如下图所示：
