The Command Pattern, alternatively referred to as the Action or Transaction pattern, belongs to the category of behavioral design patterns. It involves the conversion of a request into an independent object that encapsulates all relevant information about the request. This transformation enables the passing of requests as method arguments, facilitates the postponement or queuing of […]
The Chain of Responsibility pattern is a design technique where you have a series of objects, like a chain, and each object can decide whether it can handle a request or should pass it along to the next object in the chain. It’s like a relay race where each runner decides if they can carry

The Flyweight pattern is primarily employed to minimize the volume of object instances and, consequently, reduce memory consumption while enhancing performance. This design pattern falls within the structural pattern category, as it offers techniques for reducing the total number of objects, thereby enhancing the organization of objects within an application. The Flyweight pattern aims to
The Proxy pattern is a structural design pattern that allows an object (the proxy) to act as an intermediary or placeholder for another object, controlling access to it. It is often used to add a level of control or optimization to the interactions with the real object, such as lazy loading, access control, or logging.
A Facade is a structural design pattern that acts as an interface to a larger and more complex set of classes, simplifying the interaction with those classes by providing a unified and simplified interface. It hides the intricacies and complexities of the underlying system, making it easier for clients to work with. Computer graphics involve
The Decorator pattern belongs to the category of structural design patterns. It provides a way to enhance the functionality of objects by enclosing them within wrapper objects, which in turn, impart additional behaviors to these objects. When developing a reporting system, you need to provide flexibility for users to customize the content and appearance of
The Prototype pattern is a creational design pattern that focuses on creating new objects by copying an existing object, called the prototype, rather than using constructors. This pattern is particularly useful when creating objects that are similar to existing ones, as it promotes code reusability and reduces the overhead of repeatedly initializing objects from scratch.
