What I am trying to do:
I want to use the java.util.Properties class to save configuration
information to a persistent data file.  The properties class allows this
type of saving using and Input or Output Stream.

Some of the information I save is numerical data.  For example, I may
save a sequential number called bookID.  whenever a book object is
instantiated, the bookID is read from the Properties file, incremented
by one, and then is saved to the Properties file (somewhat similar to an
AutoNumber generator in a database).

Problem:
The Properties Class saves information as a key-value pair as in a hash
table.  The problem is: the arguments are Objects(Strings).  The number
I increment is a long.  I cannot figure out how to save the long integer
to the hashtable and then increment it each time.  I have tried casting,
the Long wrapper, etc. and cannot get this to work.  I simply want to be
able to save the long int and then retrieve it to increment later.  With
String, the incrementing in concatinated rather than added.


CODE SNIPPET
   /**
    <LI>
    bookID = sequentially ordered number assigned to each book
    */
    public String getbookletID()
    {
     return bookletID ;
    }

    public void setbookletID(String t)
    {
     bookletID = t ;
    }

    public void createbookletID()
    {
     Properties ids = new Properties() ;

     try
     {
      FileInputStream idfile = new FileInputStream("idgenerator.cfg") ;
      ids.load(idfile) ;
      idfile.close() ;
     }
     catch (FileNotFoundException e)
     {
      ids.put("bookletID" , "10") ;
     }
     catch (IOException e)
     {
     }

     String idseed = ids.getProperty("bookletID") ;


     //idseed = idseed + 1 ;
     //bookletID = idseed  ;

     ids.put("bookletID", idseed) ;
     bookletID = idseed + 1 ;


     try
     {
     FileOutputStream idfile = new FileOutputStream("idgenerator.cfg") ;

     ids.save(idfile, "ID Number Seeds") ;
     idfile.close() ;
     }
     catch (FileNotFoundException e)
     {
     }
     catch (IOException e)
     {
     }
    }
