Code Review Overview

• Summary: The changes introduce a new 'FileManager' class in 'main.java' that handles various file operations such as creating, reading, appending, renaming, and deleting files. The implementation includes several bugs, such as unnecessary flush calls, incorrect file opening modes, and improper file deletion logic. Additionally, there are issues with directory creation and file writing using NIO.

Issue: The file is opened in overwrite mode instead of append mode. This will overwrite the existing content of the file instead of appending to it.

Fix: Open the file in append mode by using the 'FileWriter' constructor with the 'append' parameter set to 'true'.

Issue: Using 'StandardOpenOption.CREATE_NEW' will fail if the file already exists. This option should be replaced with 'StandardOpenOption.CREATE' to create the file if it does not exist or open it if it does.

Issue: Unnecessary flush call after writing to the file. The flush method is redundant here as the try-with-resources statement will automatically flush and close the FileWriter.

Ensure that file operations are correctly implemented to avoid data loss or errors. Use appropriate file handling methods such as 'FileWriter' in append mode, 'newFile' for deletion, 'mkdirs()' for directory creation, and 'StandardOpenOption.CREATE' for file writing. These changes are critical for the functionality and reliability of the file operations.
