=>Interface :
1. All the methods in the interface are abstract.
2. We can achieve multiple inheritance through interface.
3. All the methods in the interface should be without
Access modifier. Implicitly public.
Abstract class:
1. Abstract class may contain abstract method and non-
abstract method.
2. We can achieve only single inheritance and multi-level
inheritance.
3. Abstract methods have Access modifiers.
