Note that there is one method already defined: Application , which is
the constructor for the application object. The first line calls the
constructor for Application’s superclass (which is the class
WebApplication). The second line prints a message, which you see
in the Launch panel when you launch your application.
2. After the call to super , enter this code:
allGuests = new MutableVector();
This statement initializes allGuests to be a new object of class
MutableVector. This class is the Java equivalent of the Objective-C
class NSMutableArray, which provides an interface that allows you to
add, change and delete objects from an array.
