Java_猜数字

import javax.swing.JOptionPane;
public class GuessNumber
{     
     public static void main (String args[ ])
     { 
           guess();
      }
      static void guess(){
       System.out.println("给你一个1至100之间的整数,请猜测这个数");
           int realNumber=(int)(Math.random()*100)+1;
           int yourGuess=0;
           String str=JOptionPane.showInputDialog("输入您的猜测:");  
           yourGuess=Integer.parseInt(str); 
           while(yourGuess != realNumber) //循环条件
           {
              if(yourGuess>realNumber) //条件代码
               {
                   str=JOptionPane.showInputDialog("猜大了,再输入你的猜测:");
                   yourGuess=Integer.parseInt(str); 
               }
             else if(yourGuess<realNumber) //条件代码
               {
                   str=JOptionPane.showInputDialog("猜小了,再输入你的猜测:");
                   yourGuess=Integer.parseInt(str); 
               }
           }
          System.out.println("猜对了!");
      }
}

其实是填代码填上去的...
