Setting up the Environment
3 Lectures 18:30

In this lecture, we will understand how to download the JDK and install it. Also, we will work on setting the required environment variables.

Preview 09:47

In this lecture, we will download Eclipse IDE and extract it. Also, we will open the Eclipse IDE and ensure that it is pointing to the JDK that we installed.

Downloading and Extracting Eclipse IDE

Class & Objects
3 Lectures 25:46

Object Oriented Programming is Real World Programming where we mimic the real world interaction in a computer system.

What is Object Oriented Programming?
03:36

What is a Class?

  • It is a template or blueprint of what it contains (State & Behaviour).
  • Logical Entity.

What is an Object?

  • Object is an instance of a Class (When you give life to a Class).
  • Physical Entity (Memory is allocated once you create an Object).
What is a Class, Object & How to create one?
14:57

In this lecture, we will understand what happens when an object is created. Also, we will discuss on the scenario where more than one object reference point to the same object.

Packages & Access Specifiers
3 Lectures 25:02

Packages:-

A Package is a namespace that organizes a set of related classes and interfaces.

Advantages of using package:-

  1. Java package is used to categorize the classes and interfaces so that they can be easily maintained.
  2. Java package provides access protection.
  3. Java package removes naming collision.
Packages
07:16

Access Specifiers (Controlling Access):-

Access Specifiers determine whether other classes can use a particular class, particular field or invoke a particular method.

At a class level, we have two access specifiers:-

  1. Default - access the class only within the package
  2. Public - access the class not only within the package but outside the package as well (anywhere).

At a data member and method level, we have the following access specifiers:-

  • Private - access only within the class only.
  • Default - access only within the package.
  • Protected - (We will discuss later)
  • Public - access anywhere (both inside and outside)
Access Specifiers
11:10

Encapsulation in Java is a mechanism of wrapping the data (variables) and code acting on the data (methods) together as as single unit.

In encapsulation the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class, therefore it is also known as data hiding.

To achieve encapsulation in Java:-

  1. Declare the variables of a class as private.
  2. Provide public setter and getter methods to modify and view the variables values.

OOPS Part 1:- Constructors, Method Overloading, This reference
3 Lectures 27:32

Constructor is a special type of method that is used to initialize the object and is automatically invoked when the object is created.

Constructor name must be same as its class name & Constructor must have no explicit return type.

There are two types of constructors namely:

  • Default constructor (no-arg constructor)
  • Parameterized constructor
What is Constructor?
08:59

Method Overloading

If a class have multiple methods by same name but with different signatures, it is known as Method Overloading.

What does signature mean?

  • Number of arguments
  • Data type of arguments
  • Order of the arguments

It does not consider the return type

Method overloading increases the readability of the program.

OOPS Part 2:- Relationships
7 Lectures 48:58

Relationships between classes

There are two types of relationships between classes:-

1) Is a relationship (Inheritance)

2) Has a relationship (Aggregation)


Class Employee{

}

Class FullTimeEmployee extends Employee{

}

Class PartTimeEmployee extends Employee{

}
