#4 Core Java OOP Mastery: Inheritance, Abstraction, Polymorphism, Encapsulation & POJO Class
#4 Core Java OOP Mastery: Inheritance, Abstraction, Polymorphism, Encapsulation & POJO Class
Welcome to the fourth video in our Core Java Training Series! In this session, we dive deeper into the world of Object-Oriented Programming (OOP), exploring advanced concepts like inheritance, abstraction, polymorphism, and encapsulation. To enhance your practical understanding, we also cover the creation of a POJO class and the use of the toString() method.
What This Video Covers:
Inheritance in Depth
A detailed recap of inheritance, emphasizing its benefits in code reuse and hierarchy design.
Explore examples of single, multi-level, and hierarchical inheritance.
Learn about the super keyword and its role in accessing parent class methods and constructors.
Abstraction in Java
Understand what abstraction is and why it is crucial for hiding implementation details.
Learn how to create abstract classes and methods.
Discover the difference between abstract classes and interfaces and when to use each.
Polymorphism Simplified
Dive into the concept of polymorphism and its two main types:
Compile-time polymorphism (method overloading).
Runtime polymorphism (method overriding).
See practical demonstrations of polymorphism in action, showcasing its power in making code flexible and scalable.
Encapsulation Explained
Understand encapsulation as the practice of bundling data and methods within a class.
Learn how to achieve encapsulation by using private variables and public getter and setter methods.
Discover the role of encapsulation in data protection and modular programming.
Introduction to POJO Class
Learn about POJO (Plain Old Java Object) classes and their importance in Java programming.
See how to create a POJO class with private variables, a no-argument constructor, and getter and setter methods.
Explore the toString() method and its role in representing object data as a string for debugging and logging purposes.
Key Highlights:
Comprehensive explanations of OOP principles with real-world examples.
Hands-on coding demonstrations of abstraction, polymorphism, and encapsulation.
Step-by-step creation of a POJO class and implementation of the toString() method.
