The application currently uses an IDatabase interface to connect to a database, but a new feature requires data from a web API that uses a different interface. An adapter pattern can be implemented to adapt the web API interface to the IDatabase interface, allowing the existing code to use the web API without modification. The adapter pattern implementation would contain classes that implement the IDatabase interface by delegating the method calls to corresponding methods on the web API interface.

1. Suppose you have an existing application that uses a database to store and retrieve data. The
application is built using an interface called IDatabase, which has methods: connect,
executeQuery, and disconnect. Example usage:
Now, you want to add a new feature to the application that requires data to be fetched from a web
API. However, the web API has a different interface that you cannot change. It has methods:
openConnection, sendRequest, and closeConnection. Use Adapter Pattern to adapts the web API
to the IDatabase interface to fit the existing code without modifying it. Instructions: Choose either
C++ or Java You do not need to implement the real logic in the method body. It's ok to use pseudo
code. For example: public void openConnection() { some logic to open the connection} The focus
is not to have a running program but show each required piece of Adapter Pattern and how they
are connected. You can use a text editor instead of IDE to write the code. All classes can be put in
one file.
