Java使用break关键字循环猜数字游戏

import java .util.Random;
import java.util.Scanner;
public class Forbreakbigg{
	
  public static void main(String[]args){
	  
	  Random ra = new Random();
	  int ib = ra.nextInt(100) + 1;
      for(;;){
			  System.out.println("请输入一个正整数");
			  
			  Scanner sc = new Scanner(System.in);
			  
			  int ia = sc.nextInt();
				
				  if (ia > ib){
					  System.out.println("猜大了");
				  }else if (ia < ib){
					  System.out.println("猜小了");
					  
				  }else {
					  System.out.println("猜对了");
					    break;  //跳出并结束循环
				  }
					  

				 
				  }
			  
		  
        
	  }

 }
