What is Object Oriented Programming Language in Java?

Object Oriented Programming Language
Object-Oriented Programming Languages

  • Oops, are the set of tools and methods that enable software engineers to build reliable software, user-friendly, maintainable, well documented, reusable software.
  •  A system that fulfills. the requirements of its users.
  •  It is claimed that Oops provides software developers with new mind tools to use in solving a wide variety of problems. 
  • Object-orientation provides a new view of computation.
  • a software system is seen as a community of objects that cooperate with each other by passing messages in solving the complex problem.

An Oops programming language provides support for the following object-oriented concepts:

  • Objects and Classes
  • Inheritance
  • Polymorphism and Dynamic binding

What are the Principles of object-oriented programming?

Object orientation is of the programming styles or methodologies. As far as application development is concerned, the following are the important object-oriented features.

  • abstraction
  • Encapsulation
  • Inheritance
  •   Polymorphism


  • The concept of binding the data along with its related and corresponding functionalities or functions is known as encapsulation.
  • The concept of making the data available only to certain related areas or only within mentioned borders is known as binding.


  • A key feature of JAVA classes is inheritance. Inheritance allows creating classes that are derived from other classes so that they automatically include some of its "parent's" members, plus it's own.
  • The concept of getting the properties of one class to another class is known as inheritance.


  • Poly means many and morphism means forms (functionalities), so the concept of defining multiple functionalities or methods with the same name associated with the same object is known as polymorphism.

Below are some advantages of OOPS.

  1. The principle of data hiding helps the programmer to build highly-secured programs That cannot be invaded by code in other parts of the program.
  2. It is possible to have multiple instances of an object to co-exist without any Interference
  3.  Object-oriented programming can be easily upgraded from small to large environments.
  4. Software complexity can be easily managed by using Oops.
