What are 4 Pillars of Java OOPs Concepts? OOPs (Object-Oriented Programming System) is a programming concept, methodology, or paradigm, that is a core of Java programming used to design programming using classes and objects. The OOPs concepts in Java build on the four main principles.- Encapsu...

let’s take the learning journey ahead; therefore, today we are going to discuss theOOPs conceptin Java. The earlier programming language was the language of hardware or simply machine; a highly skilled programmer was needed to write a program to run on those machines. In this ...
It provides more security as the concept of encapsulation is present in OOPs. Adding new functions or data is not simple. It is easy to add more data or functions to OOPs. This programming system is not based on the real world. It is based on the real world and contains real-world ent...

The same concept is applicable in the programming implementation of the Abstraction. Although different programming has a different syntax of implementation of Abstraction. But the most popular programming languages likeJAVAuse a keyword calledabstractwhich applies to the class and methods to make a clas...
