Description

Note:- Some lectures in this course are taken from my previous Java course i.e "Java for Beginners in 2 hours: Build a Banking Application" as those were the exact same concepts.

This course is a total hands-on programming course with no power-point presentations.This course is going to teach you all core Java object-oriented concepts in a short time.Object-oriented programming(OOP) paradigm is based on the concept of objects. So when we develop any application using object-oriented concepts we basically think only in terms of objects. Almost anything can be represented as an object in Java.

This course isgoing to teach you how to think in terms of objects while programming. It is also going to teach you what happens behind-the-scenes when we create an object, how objects are created and stored in memory, object lifecycle etc. Apart from this you are going to understand all other important object-oriented concepts like inheritance, polymorphism, interface, abstract class etc and also understand why they are used.

Every single concept is explained with the help of a program. This course is suitable for anyone who has some basic knowledge of Java like variables, datatypes, loops, if conditions, methods, arrays etc and who has not yet explored the object-oriented side of the Java programming language.

This course also has a mini project at the end which a console-base Quiz Application. This application is designed using object-oriented approach and will be a good revision of the entire course as a lot of concepts will be covered in it.

After completing this course you will have a clear idea about object-oriented programming and  you can start writing Java console-based applications using OOP concepts. You may also be able to answer exam questions or interview questions based on object-oriented concepts. This course is short and sweet and requires only 2-3 hours of your time.  

Some of the key points regarding this course:

  • Total hands-on programming experience.
  • All core Java object-oriented concepts covered.
  • Every concept explained with the help of a program.
  • Mini-project at the end which covers a lot of object oriented concepts.
  • Requires 2-3 hours of your time.


I believe you will enjoy this course and make the most of it. Happy Coding :)

Who is the target audience?
  • Students or programmers with some very basic knowledge of programming
  • Suitable for anyone who has started with Java and wants to learn Object-Oriented programming in detail
  • Not suitable for experienced or advanced Java programmers

Java/JSF developer

I have around 5 years of programming experience. My area of expertise is Java.

 I have completed my Bachelor’s in Computer Science and a Master’s in Computer Applications from a reputed institute.

 I am currently working in a leading US-based financial firm as a Java/JSF developer.

Ever since I started coding, I have done a lot of projects in various technologies like C++, HTML/CSS, Javascript, PHP, Java, Spring Framework, Struts, JSF  etc.

Since my college days, I used to help out my friends with a lot of programming concepts and with time I realized that I was actually enjoying teaching. And so I decided to take my teaching passion to the next level and share my knowledge with as many people as possible with this platform.
