Encapsulation is one of the four fundamental OOP concepts. Its a concrete method"I am in Super class and I am not an abstract method. Abstraction is a simple representation of a complicated situation. Therefore, to send an e-mail you just need to type the content, mention the address of the receiver, and click send.Likewise in Object-oriented programming, abstraction is a process of hiding the implementation details from the user, only the functionality will be provided to the user.

The other three are inheritance, polymorphism, and abstraction.Encapsulation in Java is a mechanism for wrapping the data (variables) and code acting on the data (methods) together as a single unit.
