CS21 Week4 In-Class Exercises

1. Create a week4 subdirectory in your cs21 subdirectory, and from your week4 subdirectory, copy over my week4 files:

   % cd                # remember you can use ls and pwd to figure out where you are in the directory tree
   % cd cs21
   % mkdir week4
   % cd week4
   % pwd                # should list /home/yourusername/cs21/week4
   % cp ~newhall/public/cs21/week4/* .   
   % ls
   Makefile  QuadDriver.java  Quadralateral.java  Student.java  StudentDriver.java
   

   We will start by opeing up Student.java in vim (or emacs), and looking at it together.
