1.Why Map interface doesn’t extend Collection interface?Set is unordered collection and does not allows duplicate elements.List is ordered collection allows duplicate elements.Where as Map is key-value pair.It is viewed as set of keys and collection of values.Map is a collection of key value pairs so by design they separated from collection...

We can not override private methods in java.The basic inheritance principle is when we are extending a class we can access all non private members of a class so private members are private to that class only we can not access anywhere outside the class if we declare anything as private.Know more information about access specifiers here Class...

Yes we can create a class as static. But class should be inner class or nested class.We know how to create static methods, static variables and static blocks.As Java Supports defining a class within a class we can create a static inner class inside a class.This inner static class inside a class can access static members of outer class even its...
