The blog explains the SOLID principles and the commonly used sofware design patterns with practical examples Additionally, Low-Level designexamples are included to bolster the learning!
The Strategy design pattern is a behavioural pattern that defines a family of algorithms, encapsulates each one, and makes them interchangeable. This pattern allows a class’s behavior to be selected at runtime. Key Concepts Strategy Interface – Defi...
The Observer Pattern is a behavioural design pattern where an object (Subject) maintains a list of dependents (Observers) and automatically notifies them of state changes. Observer pattern has the following characteristics: One-to-Many Relationship:...
Behavioural design patterns focus on communication between objects, defining how they interact while promoting flexibility and loose coupling. These patterns help manage complex control flows, encapsulate algorithms, and delegate responsibilities eff...
The Composite Design Pattern is a structural pattern that allows us to build complex tree structures where individual objects and groups of objects are treated uniformly. Concept It provides a way to compose objects into tree structures to represent ...
The Bridge design pattern is a structural pattern that helps separate an abstraction from its implementation, allowing both to evolve independently. It is useful when we have multiple dimensions of change in our system. Key Concept Abstraction: Defi...
The Decorator Design Pattern is a structural design pattern used to dynamically extend the functionality of objects without modifying their original implementation. It allows wrapping objects with additional behaviour at runtime. Key Characteristics ...
The Proxy Pattern is a structural design pattern that provides a proxy (intermediary) to control access to an object. This proxy can perform additional operations such as lazy initialisation, access control, logging, security checks, or performance o...
The Flyweight Design Pattern is a structural design pattern that reduces the number of objects created, improving memory efficiency and performance. It does so by sharing objects that are identical or similar instead of creating new ones. Essentially...
The adapter design pattern is a structural design pattern that acts as a bridge between two incompatible interfaces. Let us discuss an example to understand the above detail. We will have a system to use an existing API without modifying it by conver...
