进阶版《结对编程》

  上次说到了结对编程这个话题，但是匆匆几句，写的不尽人意，这一次，我将为大家带来详细的结对编程体验感受~~~

  首先，介绍一下我的结对编程伙伴——陈小宇，他是一个名副其实的编程高手。以下是他的博客地址：http://www.cnblogs.com/cxyc 

 附上一张我们在完成任务的过程中的留影~~

  在课题的选择中，我们选择了四则运算这个课题，相对于大三的我们来说还是比较简单的。但是一旦开始做起来，才发现问题多多。对于变量的命名、任务分配、进度调整....等等困难接踵而至，让我们措手不及。但最后我们都通过及时的交流克服了这些困难。

下面是我们的作品源码：

package com.cj;

import java.util.Random;

public class Out {
    private int a, b;
    private int i;
    private String operator[]={"+","-","×","÷"};
    
    public String getYun(){
      while(true){
        a=new Random().nextInt(100);
        b=new Random().nextInt(100);  //产生随机数
        i=new Random().nextInt(4);
        
        if(i==1&&a<b){         //不能为负数
            continue;
        }
        
        if(i==3){             //不能被0除
            if(b==0){
                continue;
            }
            if(a%b!=0){      //a一定被b除
                continue;
            }
        }
        break;       
      }
      return new String(a+operator[i]+b+"=");
    }
    
    
    public  boolean panduan(String s){    //判断答案是否正确
        int i,result = 0;
        try{
            i=Integer.valueOf(s).intValue();
        }catch(Exception e){
            return false;
        }
        switch(this.operator()){
           case "+":result=this.getA()+this.getB();break;
           case "-":result=this.getA()-this.getB();break;
           case "×":result=this.getA()*this.getB();break;
           case "÷":result=this.getA()/this.getB();break;
        }
        if(result==i){
            return true;
        }return false;
        
    }
    
    public int correctResult(){     //返回正确的答案
        int result=0;
       switch(this.operator()){
        case "+":result=this.getA()+this.getB();break;
        case "-":result=this.getA()-this.getB();break;
        case "×":result=this.getA()*this.getB();break;
        case "÷":result=this.getA()/this.getB();break;
     }
       return result;
    }
    
    
    public String operator(){        //返回运算符
        return operator[this.i];
    }
    
    
    public int getA() {  //返回运算数
        return a;
    }


    public int getB() { //返回运算数
        return b;
    }
    
}
