Step #1 • Pick up copies of the assignment handout, the Tutorial Guide, and your sample copy of The Art and Science of Java (provided by Addison-Wesley).

• Work in teams of two on your laptop using whatever Java environment you ordinarily use. If you don’t have Java on your laptop, pair up with someone who does.

• Go to the web site for the Java Task Force materials at

and follow the links to the Demo Gallery and go to the section on “Simple applications using the ACM packages.”

• Download the hello.zip file, unpack it, and get it running.

Step #2 • Create a new ConsoleProgram subclass that asks the user to enter a temperature in Fahrenheit and prints the equivalent temperature in Celsius:

QuickTime™ and aTIFF (Uncompressed) decompressor

are needed to see this picture.

FahrenheitToCelsius

This program converts Fahrenheit to Celsius.Enter Fahrenheit temperature:Celsius equivalent = 100.0

• Change only the header line of the program so that your program extends DialogProgram and run it again.

Step #3 • Implement the Breakout game in stages.

Set up the bricks.1. Create the paddle.2. Create the ball and let it

bounce around.3. Detect collisions with bricks

and the paddle.4.
