Project: lab-classes Authors: David J. Barnes and Michael Kölling This project is part of the material for the book Objects First with Java - A Practical Introduction using BlueJ Fifth edition David J. Barnes and Michael Kölling Pearson Education, 2012 It is discussed in chapter 1. The purpose of this project is to illustrate object interaction and to examine some simple code. See chapters one and three of the book. To use this project, create some Student objects, then create a LabClass object. Add the students to the class using the "enrolStudent" method. Print a class list.
