Behavioural Design Patterns in Java

Behavioural Design Patterns 10 lectures 02:12:07 The Chain of Responsibility Pattern Chain of Responsibility is a behavioral design pattern that lets you avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handles it. The Command Pattern Command is a behavioral design pattern that lets you turn a request into stand-alone object, which can be used to parametrize objects with different requests, queue or log requests, and support undoable operations. The Iterator Pattern Iterator is a behavioral design pattern that lets you access the elements of an aggregate object sequentially without exposing its underlying representation. The Mediator Pattern Mediator is a behavioral design pattern that lets you define an object that encapsulates relations between a set of objects to make them independent of each other. The Memento Pattern Memento is a behavioral design pattern that lets you capture the object's internal state without exposing its internal structure, so that the object can be returned to this state later. The Observer Pattern Observer is a behavioral design pattern that lets you define a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. The State Pattern State is a behavioral design pattern that allows an object to alter its behavior when its internal state changes. The object will appear to change its class. The Strategy Pattern Strategy is a behavioral design pattern that lets you define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from the clients that use it. The Template Pattern Template Method is a behavioral design pattern that lets you define the skeleton of an algorithm and allow sub-classes to redefine certain steps of the algorithm without changing its structure. The Visitor Pattern Visitor is a behavioral design pattern that lets you define a new operation without changing the classes of the objects on which it operates.
