st.nexToken(); will get the token from str if available. how to force stringtokenizer to start searching from beginning again?  i don't think such method exist in stringtokenizer. if not, how to destroy the object strintokenizer (own garbage collecting) coz i will be using many stringtokenizer

Why bother. The GC should do its job

It will be garbage collected anyway, you needn't worry

You don't have to destroy it by youself, it will be done automatically.
You could set the reference to it to null which would indicate that it is no longer in use, or call System.gc().
It doesn't guarantee that it will be run immediately though.

To start at the beginning, just create a new StringTokenizer (with the same reference if you want).

One trick could be to always have a stringtokenizer pointing at the beginning... Clone this one when you want to rewind. Javas garbage collector

StringTokenizer stRewind = new StringTokenizer(myString, " ");
StringTokenizer st = stRewind.clone();
while(st.hasMoreTokens()) {
 String myToken = st.nextToken();
 //If you wanna rewind do:
