## Description

The Gang of Four Design Patterns are often hard to get . This book provides an easier explanation of all the 23 design patterns with use cases implemented in Java and with link to GitHub. Topics covered: Creational : Deals with how to create objects. Singleton – Create a single instance of an object. Prototype– Use an existing object by cloning it. Factory Method – Delegate creation of an object to another object. Abstract Factory – Delegate creation of a group of related objects to another object. Builder – Delegate creation of a complex object to another object. Structural: Deals with how to structure objects. Adapter – Make two incompatible interfaces work together. Bridge – Separate abstraction and implementation. Composite – Treat part-whole hierarchy the same way. Decorator – Add responsibilities to an object dynamically. Facade – Provide a single interface for a group of related operations. Flyweight – Reuse objects than creating new ones. Proxy – Protect access to an object. Behavioral Deals with how to communicate between objects. Chain of Responsibility – Allow different objects to carry out a responsibility. Command – Encapsulate requests as separate objects. Mediator – Act as a broker for communication between objects. Template – Provide basic template of an algorithm to implement. Strategy – Encapsulate different algorithms using separate objects which can be chosen at run time. State – Encapsulate state specific behavior in a separate object. Observer – Intimate group of objects when a change occurs. Memento – Allow to revert an object’s state. Iterator – Provide a generic way to iterate through collection of objects. Interpreter – Represent a grammar using an object. Visitor – Add new responsibilities to an object without changing its existing behavior. Note : The original book by the Gang of Four was referred for these posts.
