How to achieve Abstraction ?
Abstraction can be achieved in following two ways:
- Abstract Class
- Interfaces
- Abstract class is a class which is declared with keyword Abstract and this can not be instantiated.
- Can have abstract or non abstract methods
- Abstract class achieves 0 to 100% abstraction.

- Interface is a contract /rules /blue print of a class
- Interface achieves 100% abstraction.
