8.4 Creating an instance
As was suggested in the class comment, create an instance of the class and send it some messages. You
can do that by typing the code in Figure 8.5 into the Workspace and selecting it. Then use the do it
option off the right mouse button menu (middle mouse button if you have a three button mouse).
The result of running this code should be that the following is printed into the Transcript:
0
Bob was 0 but now is 1
Once you have done this and are happy with what is happening, why not try and change the method
definitions or add a new instance variable called address and define the appropriate methods for that
variable.
