What is OOPs Concept in Java?

Abstraction, encapsulation, inheritance, and polymorphism are the four major principles of Java’s object-oriented programming (OOP). Java OOP ideas enable us to design working methods and variables, reuse them whole or in part, and do so without jeopardising security. Comprehension Java’s internals requires an understanding of OOP concepts. Join Java Training in Chennai to learn more about Java basic concepts.

Java Defines OOP Concepts as Follows:

• Abstraction. Uses straightforward objects to convey complexity. We all know how to turn on the television, but understanding how it functions is not necessary to enjoy it. Abstraction in Java refers to the way less complex underlying data and code are represented by simpler entities like objects, classes, and variables. This is crucial because it helps you avoid doing the same thing repeatedly.
• Encapsulation. The act of keeping class fields private and then making them accessible through public methods. Data and code are kept secure within the class itself thanks to encapsulation, a protective barrier. We can reuse objects like code fragments or variables without enabling system-wide open access to the data.
• Inheritance. Inheritance is a special feature of Java’s Object-Oriented Programming that enables programmers to build new classes that inherit some of the characteristics of preexisting classes. By utilising inheritance, we may expand on prior work without having to start from scratch.
• Polymorphism. Enables Java programmers to use the same term to mean several things depending on the context. Method overloading is one type of polymorphism. When that happens, the code itself contains several interpretations. Method overriding is the alternative form. When that happens, multiple variations are implied by the values of the provided variables. Let’s explore this a little more.

Best Practices for OOP Concepts in Java

Java’s OOP ideas are designed to speed up development without compromising security or usability. The aforementioned recommended practises are all focused on achieving the main objective.

• DRY (Don’t Repeat Yourself): DRY, a fundamental principle of Java, states that you should never have two identical blocks of code in distinct locations. Instead, employ a single technique across all applications.
• Make all variables and methods private from the start if you anticipate your Java code changing in the future. Access to “protected” should be expanded as needed as the code evolves, but not too widely.
• Single Responsibility. The rule of thumb for Java’s OOP ideas is that a class should never have more than one capability. This prevents entanglement between various functionalities and allows the class to be called and/or extended on its own as new uses for it arise.
• Open Closed Design. Make all classes and methods non-modifiable but available to extensions. In this manner, tried-and-true code can stay static while still being changed as necessary to carry out new duties.
