OOPs in Java:-
Following are the four basic object oriented principles:-
1. Abstraction
2. Encapsulation
3. Inheritance
4. Polymorphism
1. Abstraction:- The process of providing the necessary attributes and operations, then hiding unrelated attributes and relations are called abstractions.
Example:- Take an entity called T.V. Remote, to use that entity, the main required things are how many buttons are there and what are their functionality, how many volts batteries are used. There are many basics things: therefore the end user to use. The remote have something like internal functionality –when pressed the remote button perform a tasked which is hide from end users.
2. Encapsulation:- Encapsulation the process of defining all the properties and operation of an object in an entity.
In Java:
1. You can call the entity as class 2.Variables when you are writing in the class are properties of an object and Methods are operation an objects.
3.Variables defines in the class. It should be used by method which define in the class
3. Inheritance:- The Process of defining the new entity by using existing entities, attributes and operations is called inheritance.
In Java:- We can defines as Follows
1. The process of writing a new class by usng existing class is called inheritance.
2. Existing class is called Superclass or Base class or Parents Class
3. A newly created class is called subclass or derived class or child class.
4.Polymorphism:- The operations behaving different in different situation is called the polymorphism.
In case of the remote entities, the button with red colour will be do two operations.
