The State Pattern is a behavioral design pattern that allows an object to alter its behavior when its internal state changes. The pattern encapsulates states as separate classes and delegates the state-specific behavior to these classes. This makes it easy to add new states and modify the behavior of an object without altering its structure. […]
The Mediator pattern, also known as the Intermediary or Controller, helps manage communication between different objects. It stops objects from talking to each other directly and makes them talk only through a mediator. This keeps things more organized and prevents messy connections between objects. In air traffic control systems multiple aircraft need to coordinate their
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 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
