JAVA实现简单的猜数字游戏

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();
}
}
