When using extends the subclass is extending from the superclass so that the subclass can have all the actions that the superclass has. In code.org the PainterPlus class extends from Painter.

      super();
   }
}

Describe Console, GUI differences, or Code.org differences

Making a menu in the console does not require the same design elements that GUI needs, like icons. GUI has a friendly output for someone who is expecting more user-friendly graphics. The console is more powerful, but it not as animated as the GUI. Code.org is extremely graphics oriented to engage the user, and to help them understand concepts through a bigger picture. Also console seems easier for user input for the menu.
