public class Exam3_6{     
      public static void main(String args[]){
               int number=new wanshu();
                number.giveAnswer(689);                  
          }
      }


public class wanshu{
      void giveAnswer(int a){
           int i=1,item;
           for(i=1;i<a;i++){
             item=a%i;            
           if(item==0)
              System.out.println(i);                                    
           }
           }           
      }
求大神指点迷津

int number=new wanshu();----->请问这句有错否？？？

哦，我知道了，谢谢你
