/**
 * Demonstrate a structured-programming view of a class.
 *
 * @author  Terry Sergeant
 * @version for Program Design 2
 *
 * <pre>
 * WARNING!  We are considering classes from a "structured programming"
 * viewpoint and NOT from an object-oriented viewpoint.  There is a lot
 * more to classes than these examples suggest!
 *
 * Lessons:
 * 1) Classes can be stored in separate source files and refered to as if
 *    they exist in the current source file.  (Note that class Student2 is
 *    now in a separate document called "Student2.java" ... furthermore,
 *    Student2.java gets automatically compiled whenever I compile
 *    StudentDemo2.java!
 *
 * 2) Objects can be passed as parameters ... and all pieces of the object
 *    get passed as a unit.
 *
 * 3) Furthermore, whenever we pass an object as a parameter, a copy is
 *    made of the reference, but, because it IS a reference, any changes
 *    made happen to the original ... JUST LIKE ARRAYS!
 *
