#3 Core Java OOP Basics: Variables, Constructors, Methods & Inheritance Explained


Welcome to the third video in our Core Java Training Series! In this session, we delve deeper into the fundamentals of Object-Oriented Programming (OOP) in Java, covering essential concepts like variables, constructors, methods, and inheritance. These building blocks form the core of writing efficient and reusable Java code.

What This Video Covers:

Understanding Variables

A quick recap of variable types: local, instance, and static.
Learn the difference between these variable types and when to use each.
Practical coding examples to demonstrate variable scope and behavior within a class.
Introduction to Constructors

Learn what constructors are and why they are used in Java.
Understand the default constructor provided by Java and how to create parameterized constructors.
See constructors in action with examples, including initializing object properties at the time of object creation.
Working with Methods

Understand the structure of a Java method: method name, parameters, and return type.
Learn about method overloading: creating methods with the same name but different parameter lists.
Practical demonstrations of writing and calling methods, including static and non-static methods.
Inheritance in Java

Introduction to inheritance, a key pillar of OOP that enables code reusability.
Understand the syntax for extending a class using the extends keyword.
Explore examples of single-level and multi-level inheritance.
Learn about method overriding and how it allows child classes to redefine methods from the parent class.
Key Highlights:

Hands-on demonstrations of how constructors and methods enhance object creation and functionality.
Practical examples of inheritance, illustrating how to avoid code duplication and make your programs more modular.
Clear explanations and real-world scenarios to help solidify your understanding of these concepts.
