       This week On my Blog, I want to talk about a design pattern. The One I want to focus on is Adapter Design Pattern. Adapter design pattern Convert an interface of a class into another interface clients expect. The adapter lets classes work together that couldn’t otherwise because of incompatible interfaces. The adapter design pattern is a structural design pattern that allows two unrelated/uncommon interfaces to work together. In other words, the adapter pattern makes two incompatible interfaces compatible without changing their existing code. Now Let’s take a look at an example that shows how the design works. From the blog, I used it provided a diagram that I think is helpful to understand the design pattern. In this diagram, Socket wrenches provide an example of the Adapter. A socket attaches to a ratchet, provided that the size of the drive is the same. Here a Ratchet is ½ in size and the socket is ¼ without using an adapter you cannot connect the ratchet and socket together.
