Dependency Inversion Principle (DIP), Dependency Injection (DI), and Inversion of Control (IoC) are pivotal concepts in software development, shaping the architecture and flexibility of modern applications. What is a dependency? A state where one class depends on another is called dependency or coupling. Example Class A is dependent on Class B, i.e. Class A has to create … Read more
Design patterns play a crucial role in enhancing code quality, maintainability, and scalability. One of the most influential collections of design patterns is the Gang of Four (GoF) patterns, encapsulated in the seminal book “Design Patterns: Elements of Reusable Object-Oriented Software.” What are Design Patterns? Design patterns are proven solutions to common problems encountered in … Read more
A bloom filter is a probabilistic data structure that is based on hashing. It is extremely space efficient and is typically used to add elements to a set and test if an element is in a set. However, the elements themselves are not added to a set. Instead, a hash of the elements is added … Read more
The flyweight design pattern provides a framework for minimizing memory usage and computational overhead by intelligently sharing common elements among objects. In this blog post, we embark on a journey to explore the principles of the Flyweight pattern, dissect its key components, and unveil its real-world applications. Join us as we delve into the intricacies … Read more
The world of software design is filled with various architectural patterns that help developers create robust and maintainable code. One such pattern that plays a crucial role in managing object behaviour is the Proxy Design Pattern. In this blog post, we’ll delve into the fundamentals of the Proxy Design Pattern, understand its purpose, and explore … Read more
The State Design Pattern is a behavioural design pattern that allows an object to alter its behaviour when its internal state changes. This pattern is particularly useful when an object transitions through different states, and its behaviour needs to change accordingly. In this blog post, we’ll explore the State Design Pattern, its components, and how … Read more
Interpreter Design Pattern is particularly powerful when dealing with complex grammatical structures or when implementing languages. In this blog post, we’ll dive into the intricacies of the Interpreter Design Pattern, exploring its definition, components, and practical applications. What? The interpreter design pattern is a behavioural design pattern that is used to define a grammatical representation … Read more
The iterator design pattern stands out as a fundamental and indispensable tool. It falls under the category of behavioural design patterns and plays a crucial role in simplifying the traversal of collections. Whether you’re a seasoned developer or a newcomer to design patterns, understanding the Iterator pattern is essential for writing clean, modular, and maintainable … Read more
