Hy Sima , It was really nice to have your mail in my
box, knocking for request...

Get in your Head...
  
  String strVar = "Hello,ahsdg,sadhf,asdf";
  StringTokenizer st = new
StringTokenizer(strVar,",");
  
 ',' is the literal or the token,this string will be
splited to individual tokens
  Ex.. Hello 
       ahsdg.....

   while(st.hasMoreTokens())
   {
     System.out.println(st.nextToken());
   }
  
Take Care
& Lots of Love
Ritesh
