This programming question is a continuation of Assignment # 5-b 1. Create the following GUI, feel free to pick any suitable colors for your GUI components Student Control Panelx Load.. Save. Maximum quizzes average: Average GPA: Enable the user (by clicking "Load. buttons) to select a binary file with student objects using a JFileChooser. Make sure to restrict the user to selects only binary files. When user picks a file, load the data into an instance of StudentTree. Find the maximum quizzes average as well as average GPA and show the numbers on the GUI Student Control Panel? ? × LoadS Save. Maximum quizzes average: 9.8 Average GPA: 3.2 The user should be able to click "Save." button to save the contents of the tree on another binary file using 3FileChooser. Make sure to handle all exceptions your code might have in an optimal way. Show error dialogs to tell the user about anything went wrong. 2. Write a report that contains the following: a. Introduction b. Problem Definition c. Design (using UML class diagrams) d. Exceptions Used e. Testing f. Team Member's Responsibilities g. Problems Faced (and how were overcome). and submit it with the complete source code.
