java实现简单猜数字游戏

import java.util.Random;
import java.util.Scanner;
public class Guess_num {

  public static void main(String[] args) {
    System.out.println("欢迎进入猜数字游戏！");
    System.out.println("请输入一个数字：（范围是0-100）");
    Random pc_game = new Random();
    int pc_num = pc_game.nextInt(101);//随机产生一个小于101的整数
    Scanner input = new Scanner(System.in);
    int count = 5;//猜的次数，可自定义
    while(count > 0)
    {
      System.out.println("您有"+count+"次机会！");
      count--;
      System.out.print("请输入猜的数字：->");
      int user_num = input.nextInt();
      if(pc_num == user_num)
      {
        System.out.println("you are right!");
        count = 0;
      }
      else if(pc_num > user_num)
      {
        System.out.println("sorry, guess small!");
      }
      else if(pc_num < user_num)
      {
        System.out.println("sorry, guess big!");
      }
    }
    System.out.println("游戏结束！");
    input.close();
