What are the principles of object-oriented programming in Java?

   The principle of object-oriented programming is known as OOPS. OOPS aims to build an app around its info. The element provides access and possible operations in its way to its resources. It is based on class and objects. A Class is like a folder containing all data and methods.

An Object, however, is an instance of a class that acquires all the class’s characteristics and methods. Join Java course In Tambaram to learn more about it.




Abstraction is the mechanism in which data and programs are specified in similar ways to their semantics and the specifics of implementation are concealed. Abstraction is about hiding important facts, and simplifying facts as applied to anything similar in the real world.

There are two types of Abstraction they are Data Abstraction and Control Abstraction.


Data Abstraction


An abstraction of data is a way of constructing more complex types of data from much simpler types-similar to real-life entities.


Control Abstraction


Control abstraction is accomplished by hiding the sequence of actions in the sense of a complex task – the logic to the task can be obscured from the customer and updated in the future without influencing the customer code in a simple procedure call.

Data and methods within classes are also referred to as encapsulation in OOPS. It Can perform conjunction with implementation hiding by access control. The product is a form of data with features and behavior. Encapsulation includes both the hiding of information and the hiding of execution. It has two types are Information hiding and implementation hiding.




The main key concept of object-oriented programming is Inheritance. Java Inheritance is the process by which an entity acquires the parent object’s characteristics and behavior. It essentially establishes a bond between parents and children between the classes. In Java, the inheritance is mainly used for code reuse and retention. The keyword used in Inheritance is “extend”. 




Polymorphism is a capacity to construct functions or reference variables in various programmatic contexts. Polymorphism is considered in java language in two main versions: static binding or method surplus and dynamic binding or system surplus
