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.

Not what I expected at all. ### ⭐⭐ Could be much better *by on Reviewed in the United Kingdom June 16, 2022* Font is extremely small and is not consistent, sometimes small, sometimes extremely small.Extremely difficult to read in places due to gray font on what paper.No page numbers. Code samples are not complete implementations , at least not for abstract factory.It’s a pity because if not for these issues it would be an extremely useful companion to the GOF book which uses Small talk as the implementation examples. ### ⭐⭐⭐⭐⭐ Everything that you need *by on Reviewed in India May 4, 2022* Design patterns is a very vast topic and it is hard to find a quick and easy-to-understand reference especially when you have less time to prepare for an interview. This book is something which simplifies learning , clarifies your doubts and helps you understand some of the major concepts related design patterns. I used this effectively during my preparation.
