The student is then responsible for continuing the work and completing the lab and testing the final application$$s complete functionality.

Students must then place the following in a single $7$zip or zip file with the name format as given in the lab assignment:

All their source files or entire IDE project directory $($which must include source files$)$

One or more screenshots of the application running

Part $1$

Create a java class FileHandler in a program that reads and writes grades data from a text file on disk and performs some simple calculations on that data in the following ways: Use a looping $($repetition$)$ construct that allows the user to enter as much grade data as possible with a sentinel to end the loop and write the data to disk and close the file.

Part $2$

Use the class you created in Part $1$ and write grades into a text file and close the file. Open the file using your class functions and read the grade data into a simple data structure of your choosing and then calculate the GPA and print of the data in a nicely formatted command line display. Use the following grade$/$GPA allocations:
