Adapter Design Pattern in Java

By | July 4, 2020

In this post, We will talk and learn about the Adapter Design Pattern in Java.

  • The Adapter design pattern falls one under structural design pattern
  • It is used so that two unrelated interfaces can work together.
  • The object that joins these unrelated interfaces is called an Adapter.

Adapter Design Pattern Example in JDK :

  • javax.xml.bind.annotation.adapters.XmlAdapter#marshal() and #unmarshal()

Below is the complete source code:

Now Let’s move towards the implementation of the Adapter Design Pattern.

Here I have taken a Scenario Where WallSocket generates 240 volts electricity by default but MobileAdapter using the Adapter Design Pattern able to generate 3 volts of electricity.

Idea is that How these two incompatible interfaces(WallSocket & MobileAdapter)  talk to each other using Adapter Design Pattern

Below is the complete source code:

Output of this client program:

Volt [volts=240]
Volt [volts=3]
