Repeat Programming Project 2, but make all of the following changes:

• Name the class MemoApplet. • Create six buttons instead of five, and arrange them as follows: The buttons are still at the bottom of the GUI (applet), with the text area above them. Hint: Use the GridLayout manager on the button panel. • When the user saves the text as memo 1, the text area should display Memo 1 saved, and when the user saves the text as memo 2, the text area should display Memo 2 saved. Hint: See Self-Test Exercise 43 of the previous chapter. • Give the text area a line wrap, so that if more characters are entered than will fit on the line, the extra characters automatically go on the next line. The applet is most easily written by making changes to the solution to Chapter 13 Programming Project 2 (MemoSaver2).
