Adapter Pattern In Java

This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces.

Adapter pattern in java. Adapter design pattern in java also known as the wrapper pattern is another very useful gof pattern which helps to bridge the gap between two classes in java. Adapter class makes classes with incompatible interfaces work together adapter design pattern is a structural design pattern among the gang of four gof article on gof patterns their types design patterns. Adapter is a structural design pattern which allows incompatible objects to collaborate. This tutorial demonstrates how to use the adapter pattern in java focusing on use cases and types of adapters class object and two ways adapter patterns.

Adapter pattern an adapter pattern acts as a connector between two incompatible interfaces that otherwise cannot be connected directly. Class diagram of class adapter pattern. It is typical for the expected interface to be created as a pure interface class especially in languages such as java before jdk 1 8 that do not support multiple inheritance of classes. Adapter pattern in java.

An adapter wraps an existing class with a new interface so that it becomes compatible with the client s interface. Since multiple inheritance is not supported by many languages including java and is associated with many problems we have not shown implementation using class adapter pattern. An adapter pattern says that just converts the interface of a class into another interface that a client wants. Full code example in java with detailed comments and explanation.

The adapter pattern deals with how the classes are composed to form larger. This article explains adapter design pattern in java with class diagrams and example code. This adapter pattern uses multiple polymorphic interfaces implementing or inheriting both the interface that is expected and the interface that is pre existing. Adapter design pattern example in jdk.

Adapter pattern works as a bridge between two incompatible interfaces. Java util arrays aslist java io inputstreamreader inputstream returns a reader java io outputstreamwriter outputstream returns a writer that s all for adapter design pattern in java. Here instead of having an adaptee object inside adapter composition to make use of its functionality adapter inherits the adaptee. As per the list of gang of four patterns adapter is a structural pattern much like proxy flyweight facade and decorator pattern in java.

In other words to provide the interface according to client requirement while using the services of a class with a different interface.
