Write a program that creates a GUI that contains a label ("Enter the data"), a text area and a button. The user types in the text area lines each containing the name of a student and an integer representing their grade. When the user clicks the button, the program should get the text from the text area and save the data into a binary file as UTF strings and as integers. Calculate the average (a double) of the grades and save it to the end of the binary file. Write a program that creates a GUI that contains a label ("Enter the data"), a text area and a button.
