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. Use a second looping construct that allows the user to open and read a disk file and retrieve grades from it. 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: A=4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+=2.3, C= 2,0, C-= 1.7, D+ = 1.3, D = 1.0, D-= 0.7, F = 0.0. Part 3: Design a JavaFX GUI application that Uses the class FileHandler class internally to input the grades data from GUI into some data structure in the application class which will then be sent to disk. Display the grade data read from a file and display it in a JavaFX GUI control element of your choosing. Explain your choice of display control element - i.e. what it is and how it works Remember to create an 'OK' button to finally terminate the GUI application.
