How am I supposed to do Exercise P1.1 and Exercise P1.2 on page 30 of our book?

From ggc

All you have to do is go to http: //ggc.javawide.org/index.php/YOUR LAST NAME/ExerciseP1_1 From their click on edit and then click on Show IDE. Once that’s done click on Generate and choose Application. Finally, all you have to do is customize the application so it can look like the problems in the book.
