You will need a FileMenuHandler class to handle the events from the FileMenu. Be sure to use getAbsolutePath() when getting the file from the JFileChooser, not getName(). Handle Exceptions Create an exception called IllegalBulbException (by extending IlegalArgumentException as shown in the lecture) and have the constructor of the Bulb throw it. For our purposes, a Bulb is illegal if the wattage is less than 5. Use a try/catch statement to catch this exception in your program, and display the erroneous Bulbs to the console (do not put them in the ArrayList). Use ArrayLists Use an ArrayList to store the unsorted Bulbs. For this project, display only the unsorted bulbs in the GUI.
