Answer Posted / alb.shah
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
