Understand the concept of constructors in Java and the purpose of using them. Also learn how to define and use constructors in our programs.

This lecture is going to teach you the concept of "Constructor Overloading" where we can have multiple constructors of the same class but with different parameters.

This lecture explains how the this() constructor call is used in a class to invoke other constructors of the same class.

This tutorial will teach you the concept of Inheritance in object-oriented programming and the advantage of using it in our programs.

Understand the concept of multilevel inheritance in Java. 

This tutorial explains how the super() constructor call is used in a child class to invoke a parent class constructor.

Understand the concept of packages in Java.

Learn the different access modifiers in Java i.e public, private and protected. These access modifiers specify the visibility of a member variable, method, constructor or a class.

Understand the concept of method overloading in Java.

Understand the concept of method overriding in Java.

This tutorial explains the concept of polymorphism which in simple terms means the ability of any entity to take many forms.

Understand the concept of an abstract class and the purpose of using it. 

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

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

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.

Understand the concept of 'static' keyword in Java.

Understand the concept of 'final' keyword in Java and where it can be used.

Understand the concept of reference casting in object-oriented programming.

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

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).

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

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

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.

This tutorial explains the concept of object finalization in the object lifecycle. The finalize() method is used to perform object finalization.

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.

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

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.

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

In this tutorial, we run the Quiz Application and verify if we get the correct output.

In this tutorial, I conclude the course and give some general tips.
