JAVA Design Patterns

Gang of Four Design Patterns

Which GOF design patterns contains this repository?

Creational Design Patterns

• Abstract Factory -> Allows the creation of objects without specifying their concrete type.
• Builder -> Uses to create complex objects.
• Factory Method -> Creates objects without specifying the exact class to create.
• Prototype -> Creates a new object from an existing object.
• Singleton -> Ensures only one instance of an object is created.

Structural Design Patterns

• Adapter -> Allows for two incompatible classes to work together by adding an interface.
• Bridge.
• Composite -> Takes a group of objects into a single object.
• Decorator -> Allows for an object’s behavior to be extended dynamically at run time.
• Facade -> Provides a simple interface to a more complex underlying object.
• Flyweight.
• Proxy.

Behavior Design Patterns

• Chain of Responsibility.
• Command -> Creates objects which encapsulate actions and parameters.
• Interpreter.
• Iterator -> Accesses the elements of an object sequentially without exposing its underlying representation.
• Mediator.
• Memento.
• Observer -> Is a publish/subscribe pattern which allows a number of observer objects to see an event.
• State.
• Strategy -> Allows one of a family of algorithms to be selected on-the-fly at run-time.
• Template Method -> Defines the skeleton of an algorithm as an abstract class, allowing its sub-classes to provide concrete behavior.
• Visitor.
