  Lab 3: Data Definitions with Containment
  
  Start by looking at the classes in the textbook that represent
  the the clock time. The ClockTime class is defined on page 21.

  Open the file lab3-4.java and in the Examples class make examples of
  the ClockTime data as follows:

  -- the time is 8:15 in the morning

  -- the time is 4:35 in the afternoon

  -- Make two examples of {\tt{ClockTime}} data and ask your
       partner to tell what time do these examples represent.
