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 in vector instance orders defined on previous foil.
There are methods for indexing vectors. Like arrays, the indexing is zero-based.
  • x = v.elementAt(i);
  • v.setElementAt(x,i);
The length of the Vector can be obtained:
  • int size = v.size;
