## Adapter Design Pattern

### Ex $1$

Suppose you are working on a project to develop a mobile application that displays weather information from various sources. The application is expected to display weather data in a consistent and user$-$friendly format, regardless of the source of the data.

Your task is to create an adapter that can be used to translate data from different weather APIs into a standardized format that can be used by the mobile application. The adapter should perform the following tasks:

$1.$ Map the fields in the different weather APIs' data models to a common data model used by the mobile application.

$2.$ Convert the different weather APIs' data formats to a standard format that can be used by the mobile application.

$3.$ Provide a consistent interface for the mobile application to access weather data from different sources, without the application needing to know the details of each API's data model or format.

$4.$ Handle any errors or exceptions that occur during the data translation process, to ensure that the mobile application is not affected by issues in the weather APIs.

To complete this exercise, you will need to use the adapter pattern to create a new component that can intercept requests for weather data from the mobile application and provide a translation mechanism for different weather APIs. You will also need to use advanced techniques for data mapping and transformation to ensure that the adapter can handle the complex data structures and mappings between the different APIs.

In addition, you may need to consider issues such as data integrity, performance, and scalability to ensure that the adapter is robust and can perform well in a production environment. You may also need to work closely with the teams responsible for the different weather APIs to ensure that the adapter meets their needs and requirements.
