Definitions:

Encapsulation

Encapsulation is an object-oriented programming concept involving the bundling of data with the methods that operate on that data, restricting direct access to some of the object's components.

Abstraction

A fundamental concept in object-oriented programming that hides the complexity of a system by displaying only essential features to the user, allowing focus on what an object does instead of how it does it.

Polymorphism

A concept in object-oriented programming that allows methods to do different things based on the object it is acting upon, enabling objects of different classes to respond to the same method call.

Comparable Interface

The Comparable interface in Java is used to order objects of user-defined classes.
