02:59

Understand the concept of abstract methods and purpose of using it.

Abstract Method
04:39

This tutorial will teach you the concept of interface in Java and why it is used.

Interface
03:06

In Java multiple class inheritance is not supported but what if we want to implement a similar functionality in our programs? This tutorial explains an alternative way of achieving multiple inheritance using interfaces.

Alternative to multiple inheritance in Java

Write a program to search for a particular object in an object array using an ID. 

Searching for an object in an object array
03:55

When a class is written inside another class then it is known as nested class. This tutorial explains the concept of nested classes along with its types (static and non-static).

Nested class

Understand the concept of an automated process known as garbage collection in Java.

Garbage Collection
02:08

Understand the the concept of reachable and unreachable objects and also learn how the garbage collector treats them.

Reachable and Unreachable Objects
05:08

What if we want to make an object unreachable so that it can be garbage collected?. This tutorial explains the different ways in which we can make an object unreachable.

How to make an object unreachable?

+ Project: Quiz Application
7 lectures 25:43

This tutorial explains how to take input from the user. There are 2 common ways in which we can take input from the user i.e by using Scanner or BufferedReader. We are going to use the Scanner class.

Quiz Application: Part 1
04:49

In this tutorial, we write the Question and Answer classes for our Quiz Application.

Quiz Application: Part 2
05:05

In this tutorial, we write the Quiz class which is our core class for this Quiz Application. All the main application logic is placed inside this class.

Quiz Application: Part 3
05:59

In this tutorial, we write the Result class which is used for displaying the result of the quiz.

Quiz Application: Part 4

Requirements
  • Some very basic knowledge of Java like variables, conditional statements, looping statements, arrays, methods is expected
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 this course is for:
  • 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
