Foil 25 Methods for Vectors

From Java Tutorial, July 1, 1996 CEWES Tutorial, CPS606, JSU Class CSC499 -- July 22-25 1997, Fall 97. by Nancy J. McCracken,Geoffrey C. Fox, Tom Scavo
Elements are created with the addElement( ... ) method:
Order missouri = new Order();
orders.addElement( missouri );
The object missouri of type Order is automatically converted to an Object and added to Vector instance orders defined on the previous foil.
There are methods for indexing vectors. Like arrays, the indexing is zero-based.
x = (Typeofx) v.elementAt(i);
v.setElementAt( x, i );
The length of the Vector may also be obtained:
int size = v.size;
