Java Project - A group of similar packages
Java Package - A group of similar classes
Java Class - blueprint/template
Java Object - an instance of a class
Java Method - set of statements to perform a certain action.
Java Variables - to define data fields

Four principles of OOPS
1. Inheritance
2. Polymorphism
3. Abstraction
4. Encapsulation

Inheritance

It is a process of inheriting (reusing) class members (variables and methods) from one class to another.

The class where the class members are getting inherited is called Parent/Super/Base class

The class to which the class members are getting inherited is called Child/Sub/Derived class

The inheritance between parent class and child class is achieved using the 'extends' keyword
