This vector class implements a basic extensible array. It does not implement any of the additional features of the Sun class, including list-like operations. Those operations are available in other implementors of <A HREF="../structure/List.html"><CODE>List</CODE></A> in this package. <p> Example usage: To put a program's parameters into a Vector, we would
