Adapter pattern

Imagine you have a cool toy that you really like to play with, but it needs batteries to work. However, you don't have the right kind of batteries to make the toy work, so you're not able to play with it. That's where an adapter comes in!

An adapter is a small accessory that helps you connect different things that would not normally go together. In our example, the adapter helps you connect the toy and the battery by converting the battery's energy into something the toy can use.

Now, let's talk about the adapter design pattern in computer programming. Sometimes, we have two pieces of code that we want to use together. However, they may use different interfaces or have different functionalities, which means they cannot work together without some modification.

The adapter design pattern allows us to create an adapter that acts as a mediator between two incompatible interfaces or functions. Like the battery adapter, the code adapter converts one interface or function to another so that they can interact as needed.

To create an adapter, we first define an interface that our client code can use to communicate with the adapter. The adapter then takes care of the communication with the incompatible interface or function, translating the data as necessary. In this way, our client code does not need to change, making it more flexible and easier to work with.

Overall, the adapter design pattern helps us make different pieces of code work together by creating a bridge between them. Think of it as taking two puzzle pieces that don't quite fit and using an adapter to make them work perfectly together!
