In my previous blog, I discussed the Abstract Factory Pattern , which you can read if you're interested. Today, I am going to discuss the Factory Pattern. Factory Design Pattern Factory design pattern is similar to abstract factory pattern and they both are creational design patterns. The only difference is that Factory pattern has only one factory class while abstract factory pattern can have multiple different factories which extend the main abstract factory class. So, if you want to implement an application that have multiple similar objects, you can use factory pattern. Otherwise, if you have to implement multiple different types of objects, you can use abstract factory pattern which allows you to create multiple factories.  For Factory design pattern, it is quite less complex than abstract one. Take a look at this following diagram. I used the same example for both abstract factory and factory pattern. So you can understand the difference between two of them easily. The Factor...

 There are 5 types of creational design patterns - Abstract Factory, Builder, Factory Method, Prototype and Singleton.  Abstract Factory Design Pattern Abstract Factory is used for creation of various types of similar objects. Before explanation about the structure of this pattern, take a look at the following diagram.    The Abstract Factory Pattern may seem complex at first, but once you understand its components, it becomes much easier to work with. Here's a simple breakdown of how it operates. It consists of six key components: Interface : An interface acts as a blueprint that multiple classes will implement. In this example, Food_Drink_Interface defines a food_drink ( ) method with an empty body. This method is implemented by multiple concrete classes such as Burger , Pizza , Coffee , and Tea . Abstract Factory : An abstract factory helps create related objects without needing to know which concrete class is being instantiated. In this case, Food_Drink_Fa...

Introduction 🤔🧠💡 I found myself repeatedly questioning, "What is a design pattern , and why I should use it ? ".  The professor said that using design patterns makes our code more readable, cleaner, and easier to maintain.  Despite my efforts, the concept remained abstract and unclear.  A concise and insightful quote by  Christopher Alexander ,  well-known architect,  who pioneered the concept of design patterns, clarified the idea for me. He explained that  'Each design pattern can describe an issue which happens again and again in our surrounding. Then, it also describes about the fundamental solution to that problem. In this way, you can use this solution a million times over, without every doing it the same way twice.' This quote helped to illuminate my understanding of design patterns, enabling me to better grasp their importance and application.  Who created design pattern ? Christopher Alexander, the father of design pattern - an archite...
