Understanding Classes and Objects in C#: The Building Blocks of OOP

14 October, 2024

Thank you to our sponsors who help keep this blog post free for the reader:

This month's issue is proudly sponsored by Zohirul Alam Tiemoon.

Zohirul Alam Tiemoon is a magician of OOP. He offers some excellent online courses. Whether you're a beginner or have some experience, his course will greatly benefit your programming career.

Class:

A class is a blueprint or template that defines the structure and behavior (properties and methods) of objects. It doesn't represent any actual data but describes what an object should have and what it can do.

Object:

An object is an instance of a class. It is a concrete representation of the class, containing actual data. When we create an object from a class, we are using the class blueprint to build something real.

In Summary:

A class is like a blueprint for a house.
An object is the actual house built from that blueprint.

Here are some examples:

Here are some sample code example links:

Class Object Practice01

An employee has some properties, can work 8 hours daily, and can earn a salary.

Class Object Practice02

Create a BankAccount class that includes properties for account number, account name, and balance. The class should have methods for withdrawing, depositing, and transferring funds between accounts. Ensure that withdrawals or transfers do not result in a negative balance.

Class Object Practice03

Design a Credit Card class with a maximum limit of 500K. The class should allow cash withdrawals with a daily limit of 100K and a per-transaction limit of 20K. For bill payments, there should be no limit as long as the total spending does not exceed the maximum limit of 500K.

Class Object Practice04

Design a LibraryBook class that includes properties for book title, author, and the number of copies available. The class should have methods to borrow a book, return a book, and check availability. Ensure that no more than the available number of books can be borrowed at any time.

Class Object Practice05

Design a ParkingSpot class that includes properties for spot number, vehicle type, and availability. The class should have methods to park a vehicle, remove a vehicle, and check availability. Ensure that a spot cannot be occupied by more than one vehicle at a time.
