Methods for Vectors

• 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;
