Design Patterns

Design patterns are proven, reusable solutions to common software design problems, offering structured approaches to recurring challenges in development. These patterns fall into three main categories: creational, structural, and behavioral. Creational patterns, such as Singleton and Factory, focus on efficient object creation and management. Structural patterns, like Adapter and Composite, address the organization and relationships between objects to create flexible and scalable systems. Behavioral patterns, such as Observer and Strategy, handle communication and interaction between objects to manage complex workflows. By leveraging these patterns, developers can create more maintainable, efficient, and well-architected software.

Observer

In software development, there are scenarios where objects need to communicate with each other in a loosely coupled manner. This means that when one object's state changes, other dependent objects must be notified and updated accordingly. For instance, consider a scenario where multiple objects in a system need to be informed whenever a particular objec…

Strategy

In software design, there are scenarios where a class should have the ability to alter its behavior when its internal state changes. However, using conditional statements to manage these variations can lead to code that is difficult to maintain and extend.

Abstract Factory

In software development, particularly in large-scale applications, there arises a need to create families of related or dependent objects. These objects should be able to work together seamlessly while still allowing for variation within their families. For example, imagine an application that needs to support different types of GUI components, such as …

Factory Method

When designing software systems, there are scenarios where the exact type of objects to be created may vary or need to be determined at runtime. Direct instantiation of objects using specific class constructors can lead to tightly coupled code, making it difficult to extend or modify the system.

Decorator

In software engineering, we often encounter situations where we need to add functionalities or responsibilities to objects dynamically and transparently without altering their structure. For instance, consider a scenario where you have a base object or class with a set of core functionalities. Over time, there arises a need to add additional functionali…

Adapter

It's quite usual to encounter scenarios where existing classes or components have interfaces that are incompatible with each other. This interface mismatch can hinder collaboration between these components, making it challenging to integrate or reuse code. Modifying the existing code to conform to a new interface may not always be feasible, especially w…
