when we create any interface, Object class' methods automatically loaded. I want to know Object class' methods are abstract methods or fully implemented? As examples:-
interface A
{}
class B
{
public static void main(
String... ar)
{
A aa=null;
aa.wait(); //wait is the method of Object class
}
}
I want to know here wait() method is abstract or fully implemented and how it is calling by reference of interface A. We know that in interface every method is abstract. But when we call wait() method by reference, its working. Pleas advice me why???
