Construct UML class diagrams for the Computer and ComputerDriver classes in Exercise 6.

Exercise 6

Given this Computer design program:

Use the following trace setup to trace the Computer program. Note that we have used abbreviations to keep the trace setup’s width as small as possible. Don’t forget to specify default and initial values, even if they don’t affect the final result.
