hi buddy,

if giving more than one body of abstract method in interface when want to implement it in the class could it possible to define only ane abstract method and other not using in the class even keep it only body.

Tribhuwan, I'm sorry but it's hard to follow what you mean. Can you post some code to explain what it is exactly that you want to know?

In an interface, you cannot specify a body for a method. When you create a non-abstract class that implements an interface then all methods of the interface must be implemented in the class.

I think I get what you're asking. I believe what you're trying to ask is whether an abstract class that implements an interface must give implementation code for all of the methods in the interface. (If this isn't right, feel free to correct me.)

The answer is no, but any class that extends the abstract class must implement the methods that the abstract class does not.

For example:



The interface A defines two methods. The abstract class B implements one of them, and the concrete class C implements the other.

Does this answer your question?
