⚠️ Notes

• File Handling: A temporary file is used during deletion to ensure safe file operations.
• Data Integrity: Using a $ delimiter allows for easy separation of data fields.

🛠️ Troubleshooting

• File Not Found: Ensure that Student_data.txt is in the same directory as the Java files, or it will be created on the first run.
• File Permissions: Ensure the file is writable for successful data modification.
