Digression: OO Concepts-Objects
https://docs.oracle.com/javase/tutorial/java/concepts/
Objects: Anything that has a state and exhibits behavior.
Real world objects: Bicycle, student, course, dog, university,….
Software objects: Model real-world or abstract objects (e.g. a
list).
Methods: Procedures through which objects communicate
amongst themselves. Example: Bicycle: brake, park. Dog: bark,
eat. Student: register, study.
Attributes: Variables that hold state information. Bicycle: speed,
color, owner. Dog:name, breed. Student: name, ID.

Digression: OO Concepts-Class
Class: Prototype for all objects of a certain kind. Student,
animal, university, shape, etc.
Objects: Created from a class. For example: s1, s2 are objects
from class Student.
Inheritence: A class inherits attributes and methods from its
super class. This allows hierarchical organization of classes.
Interface: A contract between a class and its users. A class
implements an interface (methods and attributes).
BITS and Purdue are objects from class University. myCircle
and mySquare are objects from class Shape.
