用java实现猜数字游戏

package Lianxi;

import java.util.Random;

import java.util.Scanner;

public class Java3GuessNum {

     public static void main(String[] args) {

         //生成一个1~100的随机数

         Random r= new Random();

         int i=r.nextInt( 100 );

         //键盘录入猜的数字

         Scanner sc= new Scanner(System.in);

         System.out.println( "请输入一个数字:" );

         int number=sc.nextInt(); //用来接收控制台录入的数字

         //只在猜对时跳出循环，程序结束

         while ( true ){

             if (number < i) {

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

             } else if (number > i) {

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

             } else if (number==i){

                 System.out.println( "恭喜你，答对了" );

                 break ;

             }

             System.out.println( "请在输入一个数字:" );

             number=sc.nextInt();

         }

     }

}
