Interfaces may be incompatible but the inner functionality should suit the need.

It catches calls for one object and transforms them to format and interface recognizable by the second object.

As the name suggests, we use Adapter Design pattern to make two unrelated interfaces work together. The adapter pattern is widely known in software development and used in many programming languages, e.g., Java. The Adapter Design Pattern makes objects interfaces look like something that they are not. The app downloads the stock data from multiple sources in XML format and then displays nice-looking charts and diagrams for the user. Some of the benefits of using design patterns are: Design Patterns are already defined and provides industry standard approach to solve a recurring problem, so it saves time if we sensibly use the design pattern. Previous Next CodeProjectReal life example: A very simple example is using phone charger. Adapter Design Pattern comes under the Structural Design Pattern, according this design pattern two incompatible classes working together that couldn't otherwise because of incompatible interfaces. Adapter pattern lets you wrap an otherwise incompatible object in an adapter to make it compatible with another class. It allows the interface of an existing class to be used as another interface. Adapter Design Pattern in Java: Before and after Back to Adapter description Before. A design patterns are well-proved solution for solving the specific problem/task.. Now, a question will be arising in your mind what kind of specific problem? Adapter Pattern in java. Adapter Design Pattern Example in JDK. The adapter pattern describes how to convert an object into another object which a clients expects. Here we have listed down some of widely used design pattern in Java. Design patterns in java are best practices which are used to resolve some know issues. 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. The main intention of the Adapter pattern is to make two incompatible interfaces compatible so that two different systems can inter-communicate. It is often used to make existing classes work with others without modifying their source code. The Adapter Design Pattern. Adapter is a structural design pattern that allows objects with incompatible interfaces to collaborate. Imagine that you’re creating a stock market monitoring app. Wikipedia says. In software engineering, the adapter pattern is a software design pattern that allows the interface of an existing class to be used as another interface. Design Patterns in Java. This pattern works as a bridge between two incompatible interfaces. To do this, we create a new class (the adapter) that implements the target interface. Some of the adapter design pattern example I could easily find in JDK classes are; 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. Design patterns provide a reliable and easy way to follow proven design principles and to write well-structured and maintainable code. More info, diagrams and examples of the Adapter design pattern you can find on our new partner resource Refactoring.Guru. Suppose your mobile phone needs 9 Volts of supply to get charged but main supply is 220 V which is not what you require but it can be a source and you can have something that can get 9 V out of this 220 V and supply to your phone for charging. Adapter Pattern Example Consider a scenario in which there is an app that's developed in the US which returns the top speed of luxury cars in miles per hour (MPH). Adapter pattern lets you wrap an otherwise incompatible object in an adapter to make it compatible with another class. Adapter pattern in Java. In summary, an adapter helps two incompatible interfaces to work together. This is the real world definition for an adapter. In software engineering, the adapter pattern is a software design pattern that allows the interface of an existing class to be used as another interface.
