Java Programming Basics with Examples

📘 Factory Design Pattern in Java The Factory Design Pattern is a creational design pattern that provides an object-creation mechanism without exposing the creation logic to the end user. Instead of creating objects directly using the new keyword, the factory class is responsible for object creation and returning the required object. This pattern helps achieve loose coupling and better maintainability. 🧠 Core Idea of Factory Design Pattern Create objects without exposing the instantiation logic to the client and refer to newly created objects using a common interface. 🧩 Three Main Logics in Factory Design Pattern 🔹 1. Implementation Logic Present in the subclasses Subclasses provide implementation of the interface methods 🔹 2. Object Creation Logic Present in the factory class The factory decides which object to create 🔹 3. Consumer / Utilization Logic The end user (client) accesses objects Objects are obtained only through the factory class 🛠️ Steps to Create Factory Design Pat...
