Inheritance

Inheritance

What is Inheritance?

• Its a way of deriving the properties of new class from already existing class.
• The existing class is called super class or base class or parent class
• The new class is called subclass or derived class or child class.
• Inheritance allows subclasses to inherit the variables and methods of their super class

Note

• Object class is the super class for all predefined and user define classes in java

Types of Inheritance

Single Inheritance:

• Creating sub classes from single super class is called single inheritance 

                                        

Multi level Inheritance

• A class is derived from another derived class is called Multilevel inheritance

Multiple Inheritance

• A class is derived from multiple super classes is called Multiple inheritance

Advantage

1. Application development time is very less.
2. Repetition of the code is reducing, so we can get less memory.

Thanks for your time.
