Thank you for your hard work on this project! 😊 While your code meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request:

1. Exception Handling: In the FileReaderServiceImpl and FileWriterServiceImpl classes, exceptions are caught but not rethrown with an informative message and the original exception object. This is crucial for debugging and understanding the root cause of issues.

2. Variable Name Mismatch: There is a mismatch in variable names where filePath is used instead of fileName. This can lead to confusion and potential errors in file handling operations.

3. Business Logic in Main Method: The main method currently contains business logic, which is not recommended. Refactor the code to delegate business logic to separate service classes, keeping the main method clean and focused on orchestrating the flow of operations.

4. Operation Handlers: Ensure that the processedOperations map contains handlers for all possible operations to avoid potential NullPointerException. Consider adding a check or a default handler for missing operations.

5. Data Validation: Add validation to check the length of processedData before accessing its elements to avoid potential ArrayIndexOutOfBoundsException.

6. Custom Exceptions: Consider using custom exceptions, such as InvalidDataException, instead of generic RuntimeException for more specific error handling and improved code readability.

Please address these issues to ensure the code is robust and maintainable. Once these changes are made, we can proceed with the approval. Keep up the great work, and don't hesitate to reach out if you have any questions! 🚀
