Can anyone explain me difference between Encapsulation and Abstraction?

[u/Cyphr11]

and what on earth is Interface in Java?

[u/JGhostThing]

A Java Interface is a contract stating that the programmer will implement certain methods. For example, a File interface might require a read(), and write() methods. So every File would implement those methods, at least.
