What is Adapter pattern explain?

An Adapter pattern acts as a connector between two incompatible interfaces that otherwise cannot be connected directly. An Adapter wraps an existing class with a new interface so that it becomes compatible with the client’s interface.

What type of design pattern is Adapter?

Adapter pattern works as a bridge between two incompatible interfaces. This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces.

Why do we need Adapter design pattern?

The adapter pattern is often used to make existing classes work with others without modifying their source code. This pattern converts the (incompatible) interface of a class (the adaptee) into another interface (the target) that clients require.

What is Adaptor design pattern in Java?

Adapter is a structural design pattern, which allows incompatible objects to collaborate. The Adapter acts as a wrapper between two objects. It catches calls for one object and transforms them to format and interface recognizable by the second object.

What is Adapter pattern give an example of Adapter pattern?

Example. The Adapter pattern allows otherwise incompatible classes to work together by converting the interface of one class into an interface expected by the clients. Socket wrenches provide an example of the Adapter. A socket attaches to a ratchet, provided that the size of the drive is the same.

What are the two variations of Adapter pattern?

If you do some research on the adapter pattern, you will find two different versions of it: The class adapter pattern that implements the adapter using inheritance. The object adapter pattern that uses composition to reference an instance of the wrapped class within the adapter.

Which design problems does the adapters pattern solve?

The adapter design pattern solves problems like:

How can a class be reused that does not have an interface that a client requires?
How can classes that have incompatible interfaces work together?
How can an alternative interface be provided for a class?

What is the most common use for the adapter pattern?

The Adapter pattern is a structural design pattern that enables incompatible interfaces, from disparate systems to exchange data and work together. It is extremely useful when integrating tool-kits, libraries and other utilities together.

What is pluggable adapter design pattern?

In a sense, the pluggable adapter pattern takes polymorphism (the ability of override a method in a subclass) and the Strategy Design Pattern (the ability to change the algorithm used by a method) to a new level. The key to the Pluggable Adapter Pattern is to be able to treat methods as data.

What are advantages of design pattern?

The advantages are that design patterns are solutions to repetitive problems in object orientated programming (solutions that can be re-used over and over and applied to different areas and different problems).
