From the sequence diagram Figure 2-34, draw the corresponding class diagram. Hint: Start with the participating objects in the sequence diagram.

What will be an ideal response?

Figure 5-7 depicts a sample solution. The student should figure out from the sequence diagram that there should be
access paths among all three classes. One way to ensure that these paths exist is to introduce a top-level object
2Bwatch which has aggregation associations with the other three classes.
