Class.forName(visitNoteClass).newInstance();

hi!
I need to know what this line does in detail?
Class.forName(visitNoteClass).newInstance();

++++++++++++++++++++++

      private String visitNoteClass = null;
      private HttpServletRequest request = null;
      private ActionMapping mapping = null;
...
...

      }
      public ActionForward execute() {

            VisitNoteType v = null;
            Connection conn = null;
            OraConnDispenser ocd = null;

            try {
                   v = (VisitNoteType) Class.forName(visitNoteClass).newInstance();
                   v.init(request);
                   ocd = new OraConnDispenser(null);
                   conn = ocd.getConnection();

>>u wouldnt be able to differentiate if an exception happends in Class.forName or in the newInstance()..

Not strictly true, as different subclasses of Excepetion are thrown, although it does make the code more readable/maintainable
