The Art of Inheritance, Overriding and
Method Overloading

Inheritance👇


The process of connecting one class with another class is called Inheritance. Inheritance in Java is implemented using the "extends" keyword. Inheritance is a powerful mechanism in Java that promotes code reuse and supports polymorphism, enabling more flexible and maintainable code.

Example-:


Advantage of inheritance✊

👉Inheritance allows classes to inherit fields and methods from a superclass.

 👉Inheritance supports polymorphism, which is the ability of objects of different classes to be treated as objects of a common superclass.

👉Subclasses can override methods inherited from the superclass to provide specialized implementations.

👉Inheritance allows for the extension of existing classes to create new classes with additional functionality.

👉Inheritance facilitates the organization of classes into hierarchies, which can represent real-world relationships or conceptual hierarchies.

👉Inheritance can simplify maintenance and updates to codebases by promoting a modular approach.

👉Objects of the superclass are inherited by the subclasses, but objects of the subclasses are not inherited by the superclass.

Method Overloading👇

 

When you want to keep multiple methods with the same name in the same class, you can keep those methods as separate methods by changing the parameters of those methods.  This process is called method overloading.  This process is also known as signature changing.Multiple methods in a class with the same name but with different types or numbers of parameters. Method overloading provides flexibility and makes code more readable. It allows developers to use the same method name for logically similar operations, even if the parameters differ.

Example-:


Method Overriding👇

The process of changing the body of a method inherited from a superclass to a subclass is called method overriding. To override, the class must inherit.

  Unveiling the Trinity of Standards, Objects, and Classes   Ever wondered what makes Java the superhero of programming languages? Well, it's not just about writing lines of code; it's about mastering the ABCs of Java: Standards, Objects, and Classes. 01.Standard In Java, "standard" typically refers to the Java Standard Edition (SE), which is one of the three major editions of the Java platform, alongside Java Enterprise Edition (EE) and Java Micro Edition (ME). Java SE provides the core functionality and libraries that constitute the foundation for Java development.   The Main Features   of Java Standard Edition (SE) include: 1.1.Core Libraries-:  Java SE includes a comprehensive set of core libraries that offer essential functionalities such as data structures,input/output operations, networking, and utilities. These libraries provide reusable components that simplify common programming tasks. 1.2. Platform Independence-:  One of Java's key fe...

A Guide to Object Generating, Data Types, Parameters and Arguments

Image
  A Guide to Object Generating, Data Types, Parameters and Arguments In Java programming, Object Generation involves creating objects based on classes, shaping the structure of the code. Data Types define the nature of values – numbers, words, or complex structures – ensuring accuracy and efficiency. Parameters act as instructions for functions, and Arguments are the actual values that bring these instructions to life, making code adaptable and powerful. 01.Object Generating In Java, "object generation" refers to the creation of objects, which are instances of classes in the Java programming language. Class  In Java, a class is like a blueprint or template that describes how to create objects. It defines the properties (data) and behaviors (methods) that objects of that type will have. Object  An object is an instance of a class. It's like a specific copy created based on the blueprint provided by the class. Objects have their own set of data and can perform act...

Getting Started with Design Patterns - Part 1

Image
   Design Patterns Part 1 of the Series 🚀 Let’s explore design patterns in a way that’s easy for beginners to understand! Design patterns are like tried-and-true recipes for solving common programming challenges. They help you write better, cleaner, and more efficient code. If you’re new to the concept, don’t worry – this guide will walk you through the basics step by step🎯. Let’s get started! Introduction🙋 The term design patterns is common in discussions about best practices for solving problems efficiently during software development. But really, what are design patterns? Simply explained, a design pattern represents a known solution for a frequently occurring problem in software design. They describe standardized ways to tackle recurring problems with ease and give robust codebases. The importance of the design patterns comes in that it encapsulates combined experience coming from generations of experienced developers. A design pattern allows you easily to writ...
