Understanding the adapter pattern
The adapter pattern is a structural design pattern that helps us make two incompatible interfaces compatible. What does that really mean? If we have an old component and we want to use it in a new system, or a new component that we want to use in an old system, the two can rarely communicate without requiring code changes. But changing the code is not always possible, either because we don't have access to it or because it is impractical. In such cases, we can write an extra layer that makes all the required modifications for enabling communication between the two interfaces. This layer is called an adapter.
To further understand this design pattern, let's consider some real-life examples.
