Q.5.2 Explain the importance of implementing exception handling in the Sports
Administration application.

Answer 1

In the class diagram for the given scenario, following classes can be represented:

1. Sports Organisation:
Attributes: None
Methods: None

2. Personal Assistant:
Attributes: name, schedule
Methods: manageSchedule()

3. Administrator:
Attributes: name, players
Methods: recruitPlayer(), managePlayer()

4. Player:
Attributes: name, matches
Methods: playMatch()

Relationships:
- Personal Assistant is associated with Administrator through the manageSchedule() method.
- Administrator is associated with Player through the recruitPlayer() and managePlayer() methods.

The importance of implementing exception handling in the Sports Administration application is as follows:
1. Error handling: Exception handling allows for proper handling and reporting of errors or unexpected situations that may occur during the execution of the application. This helps in providing meaningful error messages to users or administrators, making it easier to identify and fix problems.

2. Application stability: By catching and handling exceptions, the application can gracefully handle errors and prevent crashes or abrupt terminations. This ensures greater stability and reliability of the application.

3. Debugging: Exception handling provides an effective way to track and debug errors in the code. When an exception is thrown, the application can log relevant information about the error, which can be used for debugging and resolving the issue.

4. User experience: Proper exception handling enhances the user experience by displaying user-friendly error messages and guiding users on how to resolve or recover from the encountered error. This improves user satisfaction and reduces frustration.

5. Security: Exception handling can help in preventing unauthorized access or malicious activities by catching and handling potential security breaches. By properly handling exceptions related to security, the application can protect sensitive data and resources.

Overall, implementing exception handling in the Sports Administration application ensures robustness, stability, better user experience, debugging ease, and enhanced security.
