  List of OOP Concepts in Java There are four main OOP concepts in Java. These are: Abstraction.   Abstraction implies utilizing straightforward things to speak to complexity. We all know how to turn the TV on, but we don’t ought to know how it works in arrange to appreciate it. In Java, reflection implies basic things like objects, classes, and variables speak to more complex fundamental code and information. Usually critical since it lets dodge rehashing the same work numerous times. Encapsulation.  This can be the hone of keeping areas inside a lesson private, at that point giving get to to them through open strategies. It’s a defensive obstruction that keeps the information and code safe within the lesson itself. This way, able to re-use objects like code components or factors without permitting open get to the information system wide. Inheritance.  Usually, an  uncommon include of Question Situated Programming in Java. It lets software engineers make modern classes that share a fe
