What are the 4 basics of OOP?
The Four Principles of Object-Oriented-Programming (OOP):
- Encapsulation. Encapsulation is accomplished when each object maintains a private state, inside a class.
- Abstraction. Abstraction is an extension of encapsulation.
- Inheritance.
- Polymorphism.
Which two features of object oriented programming are the same?
Explanation: Encapsulation and Abstraction are similar features. Encapsulation is actually binding all the properties in a single class or we can say hiding all the features of object inside a class. And Abstraction is hiding unwanted data (for user) and showing only the data required by the user of program.
