create another class called wordgui that will be a complete jframe with a menu bar and menus. there should be two menus: one called file and another called list. the file menu should have the menu items open and quit. the list menu should have five menu items: a, e, i, o, u.
. The content pane of the GUI should have a grid layout of one row and two columns. Clicking on File > Open should allow the user to choose a file. That file should be displayed in the left column, with the lines numbered (starting at 1). When the user clicks on List a choice can be made of one of the five vowels. Clicking on a vowel should list all the words starting with that vowel in sorted order in the right column. Each word should have the line number on which it appeared. Create a class to record the word and its line number Create a class called WordLine that will have two instance variables: a String for the word, and an int for the line number on which the word appears. There should be a two-argument constructor, and error checking with an exception thrown if the line number is less than 1. You may store the WordLine objects in either an array or a linked list. The exception thrown should be an InvalidWordLineException which you can create by extending IllegalArgumentException as shown in lecture.
