Sections

  • 1

    Inheritance

    Inheritance is a core principle of object-oriented programming where a new class can inherit attributes and behaviors from an existing class.

  • 1.1

    What Is Inheritance?

    Inheritance enables subclasses to acquire properties and methods from superclasses, allowing for code reusability and a hierarchical class structure.

  • 1.2

    Why Use Inheritance?

    Inheritance is a fundamental concept in object-oriented programming that allows subclasses to inherit properties and behaviors from superclasses, promoting code reusability and hierarchical classification.

  • 1.3

    Types Of Inheritance In Java

    This section introduces the types of inheritance in Java, detailing single, multilevel, and hierarchical inheritance.

  • 1.4

    Syntax

    This section outlines the syntax for defining classes and interfaces in Java, including inheritance structures.

  • 1.5

    Example

    This section covers the fundamental concepts of inheritance, interfaces, and polymorphism in Java, essential for OOP.

  • 2

    Interface

    An interface in Java defines a contract of abstract methods to be implemented by classes, promoting flexibility and multiple inheritance.

  • 2.1

    What Is An Interface?

    An interface in Java is a collection of abstract methods which classes can implement to ensure certain behaviors.

  • 2.2

    Features Of Interfaces

    This section covers the critical features and functions of interfaces in Java, elucidating their role in enabling abstraction and multiple inheritance.

  • 2.3

    Why Use Interfaces?

    Interfaces define a contract in OOP that classes must fulfill, providing flexibility and enabling multiple inheritance.

  • 2.4

    Syntax

    This section focuses on the syntax of Inheritance, Interfaces, and Polymorphism in Java, highlighting the structure and usage of these concepts.

  • 3

    Polymorphism

    Polymorphism in Java allows objects to operate in multiple forms, enhancing flexibility and enabling method overloading and overriding.

  • 3.1

    What Is Polymorphism?

    Polymorphism in Java allows methods to be used in different ways based on object types, enabling flexibility in code.

  • 3.2

    Compile-Time Polymorphism (Method Overloading)

    Compile-time polymorphism, or method overloading, allows methods in a class to be defined with the same name but different parameters.

  • 3.3

    Runtime Polymorphism (Method Overriding)

    Runtime Polymorphism, achieved through method overriding, allows a subclass to redefine a method from its superclass, enabling dynamic method dispatch based on the actual object type.

  • 4

    Summary

    This section covers the fundamental concepts of Inheritance, Interface, and Polymorphism in Object-Oriented Programming, with examples in Java.

  • 5

    Important Points To Remember

    This section highlights the key concepts of Inheritance, Interfaces, and Polymorphism in Java, which are fundamental for creating maintainable OOP applications.
