Command pattern is used to encapsulate/wrap a command in an object so that the object can be sent as a parameter and can be used in other places. This article demonstrates Command pattern implementations in Java. Check the following examples.
Chain of Responsibility pattern is used to decouple the request and response handling. Multiple objects create a chain that is used to handle a request. This article demonstrates Chain of Responsibility pattern implementations in Java. Check the following examples.
Builder pattern is used to hide the complexity of building complex objects from the client and also this pattern is responsible for building objects step-by-step. This article demonstrates Builder pattern implementations in Java.
Abstract Factory pattern is used to generate multiple factory generators. This article demonstrates Abstract Factory pattern implementations in Java.
Bridge pattern is used to decouple implementation and abstraction. This article demonstrates Bridge pattern implementations in Java.
Composite pattern is used to handle the operation of a bunch of classes (having the same interface), to operate the same function of all items a the same time. Using Composite pattern the client can ignore the difference between the Composition and Leaf classes, and can use the composition considering the same interface. This article demonstrates Composite pattern implementations in Java. Check the following examples.
Decorator pattern is used to attach a new functionality to an existing object, without changing the existing class. This article demonstrates Decorator pattern implementations in Java.
Flyweight pattern is used to reduce the number of objects to save memory and optimize resources. This article demonstrates Flyweight pattern implementations in Java. Check the following examples.
Facade pattern is used to hide the complexity of underlying subsystems. A new layer is created as Facade, which works as an entry point for the client. This article demonstrates Facade pattern implementations in Java.
Adapter pattern is used when an interface does not match the new requirement and the existing interface needs to adapt to another interface. This article demonstrates Adapter pattern implementations in Java.
