It provides solution for helping incompatible things to communicate with each other.

Adapter pattern is never implemented when designing a new system but with the changing requirements we have deferring interfaces then adapter comes into picture.
The adapter design pattern helps to work classes together. In design, adapters are used when we have a class (Client) expecting some type of object and we have an object (Adaptee) offering the same features but exposing a different interface. Adapter pattern … Adapter design pattern is a structural pattern.Adapter pattern lets two components work together which have incompatible interfaces.It is useful if we need to implement some functionality in our application and a class already exists which provides the required functionality.But The existing class providing the required functionality has a different interface than … The object that joins these unrelated interface is called an Adapter. 1.2 Adapter Design Pattern – … The pattern includes a speciation a polymorphism which names one name and multiple forms. The Adapter acts as a wrapper between two objects. Similar to adapters in the physical world, you implement a class that bridges the gap between an expected interface and an existing class. The adapter pattern is often used to … The adapter pattern is one of the most used and well known structural patterns. This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces. Adapter pattern works as a bridge between two incompatible interfaces. Adapter is a structural design pattern, which allows incompatible objects to collaborate.. According to Wikipedia : In software engineering, the adapter pattern is a software design pattern that allows the interface of an existing class to be used from another interface. Adapter Design Pattern The adapter design pattern is a structural design pattern that allows two unrelated/uncommon... Interfaces may be incompatible, but the inner functionality should match the requirement. It is often used to make existing classes work with others without modifying their source code. Adapter design pattern is one of the structural design pattern and its used so that two unrelated interfaces can work together. The Adapter Pattern is an often-used pattern in object-oriented programming languages. To use an adapter: The client makes a request to the adapter by calling a method on it using the target interface. It works as an inter-mediator who takes output from one client and gives it to other after converting in the expected format. 1 Adapter Design Pattern 1.1 Two Way Adapter Pattern. It converts the interface of a class into another interface based on requirement. It enable two incompatible interfaces to work smoothly with each other. The visitor pattern is used when: When you have a class(Target) that invokes methods defined in an interface and you have a another class(Adapter) that doesn't implement the interface but implements the operations that should be invoked from the first class through the … Furthermore, In the adapter design pattern, we have an adapter that is responsible to mediate the communication between an outside system or service (the Adaptee) and a client. The Adapter pattern lets you create a middle-layer class that serves as a translator between your code and a legacy class, a 3rd-party class or … Use the Adapter class when you want to use some existing class, but its interface isn’t compatible with the rest of your code. It catches calls for one object and transforms them to format and interface recognizable by the second object. Structural Patterns Adapter - Do we have the right stuff but wrong interface. Say for a shape class which can use as per the requirements gathered. In programming as well, adapter pattern is used for similar purposes. It is quiet common when legacy code has to be called.
