Lab 5 - Comparators

Overview

In this lab, you will practice writing comparators, removing entries from a map and using Iterators.

You will be completing the implementation of the DoctorsOffice class you started developing last week.

Before starting, be sure your DoctorsOffice class is checked into RCS in your lab 4 subdirectory. Check it out with a lock.

Create a lab 5 subdirectory where you will do the work for this lab. Copy the DoctorsOffice.java file into this directory. Create an RCS directory in your lab 5 directory then check in DoctorsOffice.java.

Now check DoctorsOffice.java back out (in your lab 5 directory) and you're ready to start work for this week.
