programming rocks the house

It’s party time!

The mixer program brought the house down!
The DJ took your program to the World Music Mixing Expo and rocked
the house, with your name in lights! By using classes for the widgets and
creating an object oriented program, you made your good program (and
the DJ’s performance) great.
Object orientation is meant to help you create complex programs with
very little code. A lot of languages use object orientation, and not just
for graphical user interfaces. You can use objects to build web applications
or simulators or games. Any time you need to write an advanced program
but don’t want your code to turn into a tangled mess of spaghetti, object
orientation can come to the rescue!

Congratulations!
You got to the end of the book! And what a great journey it’s been. You’ve
ruled with control statements. You’ve powered-up your programs with
modular code. You’ve made graphical user interfaces that sing and, finally,
you took your coding skills to the next level with object orientation.

Well done!
