Software Design Patterns Questions Medium
Creational, structural, and behavioral design patterns are three categories of software design patterns that serve different purposes in software development.
1. Creational Design Patterns:
Creational design patterns focus on the process of object creation, providing solutions for creating objects in a flexible and reusable manner. These patterns help in decoupling the object creation process from the client code, making the system more maintainable and extensible. Examples of creational design patterns include Singleton, Factory Method, Abstract Factory, Builder, and Prototype.
2. Structural Design Patterns:
Structural design patterns deal with the composition of classes and objects to form larger structures and provide solutions for creating relationships between objects. These patterns help in organizing classes and objects to achieve flexibility, reusability, and maintainability. Examples of structural design patterns include Adapter, Bridge, Composite, Decorator, Facade, Flyweight, and Proxy.
3. Behavioral Design Patterns:
Behavioral design patterns focus on the interaction and communication between objects, providing solutions for effectively managing the behavior and responsibilities of objects. These patterns help in defining the communication patterns between objects and simplifying the interaction between them. Examples of behavioral design patterns include Observer, Strategy, Template Method, Command, Iterator, State, Visitor, and Chain of Responsibility.
In summary, creational design patterns deal with object creation, structural design patterns deal with object composition, and behavioral design patterns deal with object interaction and communication. Each category of design patterns addresses different aspects of software design and helps in solving specific design problems.
