In a large-scale application that reads data from external files, how would you design an exception-handling mechanism to not only log the issues for the developers but also to provide friendly feedback to the end-users, ensuring that the system does not crash upon encountering an exception?
- Catch exceptions at the file reading level and log them using a robust logging framework like Log4j. Use a user-friendly interface to display error messages to end-users while providing detailed logs for developers.
- Allow exceptions to propagate to the highest level of the application, ensuring that they are caught and logged centrally. Provide user-friendly error messages with detailed descriptions for end-users.
- Implement a global exception handler that logs errors and sends notifications to developers. Display user-friendly error messages to end-users using a dedicated error-handling component.
- Catch exceptions at the file reading level and log them using the standard Java logging framework. Display generic error messages to end-users, and include technical details in logs for developers to analyze.
Handling exceptions in large-scale file reading applications requires a balance between logging and providing user-friendly feedback. Option 1 suggests catching exceptions at the file reading level, which is essential for preventing crashes, and using a robust logging framework. It also emphasizes the importance of user-friendly messages. Option 2 also focuses on logging and user-friendly messages but recommends allowing exceptions to propagate, which can lead to less control over error handling. Options 3 and 4 suggest variations but may not offer as comprehensive solutions.
