Redo Project 7 using a menu for the different user choices. Based on the user's choice, display an appropriate GUI in a panel. For example, if the user selects "Add an Item" from the menu, the GUI should allow the user to enter the desired information using radio buttons, check boxes, text fields, and other such components. If the user selects "Retrieve an Item", the GUI displayed should have a text field in which the user can enter the title, and it should have a text area for displaying the information retrieved.

Modify PDButtonUI to make the changes discussed at the beginning of this appendix. Specifically:

• Provide separate buttons for "Add Entry" and "Change Entry"

• Remove the buttons "Save Directory" and "Exit".

• The file should be automatically saved whenever the window is closed.
