Catching File Exceptions in openpower-vpd-parser
In this commit, I have added code to handle file exceptions
more effectively. By implementing proper exception handling,
we can improve the robustness and reliability of the file
operations within our codebase.
Here are the key changes made in this commit:
- Introduced a try-catch block around the file operation sections.
- Within the try block, added code to perform the necessary file
operations.
- Implemented catch blocks to handle specific file exceptions.
- In each catch block, included appropriate error handling logic,
such as logging the error message or displaying a user-friendly
error message.
- Ensured that the catch blocks gracefully handle the exceptions
and prevent the program from crashing or behaving unexpectedly.
By adding this exception handling code, we can anticipate and handle
potential file-related errors gracefully, providing a smoother
experience for users and preventing any unexpected crashes or data
loss. This would also aid in debugging issues.
