觉得没问题啊,怎么执行不出来，求高手够指点！本人刚学java
class A
{
       public int i=2;
       public int j=1;
       public int sum=2;
       public int m;
       public int n;
      
       public void f()
       {
       for(m=1;m<=50;m++)
            {
              i=i+j;
              j=i-j;
              n=i/j;
              sum=sum+n;
              
             }
           }
      
   
       public void show()
       {  
              System.out.printf("%d\n",sum);
             }

}
class F
{
       public static void main(String[] args)
       {
               A aa=new A();
               aa.f();
               aa.show();
            
               
      }
}

额，我这貌似有问题，再想想！

这样的错误，咋回事啊？

知道了，这个终于执行出来了！呵呵，谢谢！

class A
{
       public long i=2;
       public long j=1;
       public  float sum=2f;
       public long m;
       public float n;
      
       public void f()
       {
       for(m=1;m<=50;m++)
            {
                i=i+j;
                j=i-j;
                 n=(float)(i/(j*1.0));
              sum=sum+n;
              
             }
           }
              
            
      
   
       public void show()
       {  
              System.out.printf("%f\n",sum);
             }

}
class F
{
       public static void main(String[] args)
       {
               A aa=new A();
               aa.f();
               aa.show();
            
               
      }
}
