Caution

nextElement()

has the side-effect  of removing  the next element from the enumeration.

If you want to make several uses of the object, you should assign  the element to a variable:

while( e.hasMoreElements() )

  {

  Object next = e.nextElement();

    ...use next...

  }

Note:

nextElement() returns an Object  which may need to be cast  to its appropriate class.

Example

Convert a Vector containing String's into a Vector of Float's by parsing each String as a float.
