Also, in this tutorial, the programs we are getting you to write are designed to be run from the command line, rather than using graphical interfaces or applets. Again, this is to make things simpler when you are starting off. Graphics and applets involve advanced Java features which we can only easily explain later when the basics are out of the way. Of course, if you want to get on with graphics straight away, you can skip forward in this tutorial.
