Behavioral Patterns
Behavioral patterns are a category of design patterns in software engineering that focus on communication and interaction between objects, defining how they collaborate and distribute responsibilities. They address common challenges in object-oriented design, such as managing complex control flows, encapsulating algorithms, and handling requests or events. These patterns help create flexible, maintainable, and reusable code by decoupling sender and receiver objects.
Developers should learn behavioral patterns to solve recurring problems in object interaction, such as implementing undo/redo functionality, managing state transitions, or handling complex workflows. They are essential in scenarios like building event-driven systems, designing user interfaces, or creating algorithms that vary independently from the objects that use them, as seen in frameworks like GUI toolkits or game engines.
