OOP is a programming paradigmthat assumes centrality in Java because it allows for codes that are modular, reusable, maintainable, or easy to develop. The most characteristic features that it uses include classes and objects, encapsulation, inheritance, polymorphism, and abstraction. Introduction to Cl...
Encapsulation is said to be providing “access control” through which we can control which parts of the program can access the members of any class and thus prevent misuse. Various access controls are public, private and protected. Difference Between Abstraction And Encapsulation :- Real World Exa...
