ABTRACT CLASS:
-------------
• It can not be instantiated
• It allow us to specify all access modifier except
Private
• A class inheriting this must implement all of its
abstract method
• A class can inherit only one abstract class at a
time.
• Abstract class can add more functionality with out
destroying child classes that were using old version.
• We can declare the following
1. Fields
2. Constructors
3. Static Constructors
4. Static Functions
5. Concrete Functions
INTERFACE :
---------
• It can not be instantiated
• It allows only public Access modifier
• A class implementing interface must provide body
for its entire member.
• A class can implement more than one interface at a
time.
• Adding of additional functionality will have an
effect on its child class due to the necessary
implementation of interface methods.
• We can not declare the following
1. Fields
2. Constructors
3. Static Constructors
4. Static Functions
5. Concrete Functions

abstract class may contain concreate methods with abstract

by default all methods in interface are public
where as abstract class can contain all modifiers except
private
abstract class involves in inheriting chain . where as
interfaces there is no need to follow inherit chain
