Overloading

[venkatesh pendharkar]

Hi ,I mam trying to compile this code &

class F 
 {
    void met(int a)
   {
    System.out.println(a*a);

   }
 };
 
class E extends F
{
   void met(long a)
   {
    System.out.println(a+a);

   }
};
 
class D
   {      
        public static void main(String args[])
{
E e=new E();
e.met(12);
 }
 
    }

i dont understand why its giving a comile time saying reference to met() is ambiguous.Doesnt compiler understand that 12 is in int so e.met(12) should call met(int a) in superclass

Also the same code works fine if we overload met() in class E

 
class F 
 {
    
 };
 
class E extends F
{
   void met(long a)
   {
    System.out.println(a+a);
   }
 
   void met(int a)
   {
    System.out.println(a*a);

   }
};
 
class D
   {      
        public static void main(String args[])
{
E e=new E();
e.met(12);
 }
    }

I dont understand how cum this code works now when methods are overloaded. Somebody please explain.

I'm not getting a compile-time error on the first code.

Venkatesh,
The 1st code compiles fine here. I dont get any error. I get an output of 144 for both the cases.
