Design patterns are essential for software development, as they provide solutions to common problems in software design. Here, we'll explore some popular design patterns.
Creational Patterns
Creational patterns focus on object creation mechanisms, providing ways to create objects in a manner suitable to the situation.
- Singleton Pattern: Ensures a class has only one instance and provides a global point of access to it.
- Factory Method Pattern: Defines an interface for creating an object but lets subclasses alter the type of objects that will be created.
Structural Patterns
Structural patterns deal with the composition of classes and objects to form larger structures.
- Adapter Pattern: Allows objects with incompatible interfaces to work together.
- Decorator Pattern: Allows adding new functionality to an object without modifying its structure.
Behavioral Patterns
Behavioral patterns are concerned with communication between objects.
- Observer Pattern: Defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.
- Strategy Pattern: Defines a family of algorithms, encapsulates each one, and makes them interchangeable.
