a problem with tokenizer

Dear friends,

the string tokenizer works with me well in the begining but how can i set the tokenizer to start processing another part if the code. see the code below :


String string = "Mike can not drive ";
.

System.out.println("\nthe token is :\n") ;

StringTokenizer stok = new StringTokenizer(string);
while (stok.hasMoreTokens())
{
System.out.println(stok.nextToken());

}


queue qu = new queue(stok.nextToken().length());




The problem is just with the last code. it seems that no tokens has been read. therfore, is there any method that read the tokens from the begining.


thanks

You shouldn't really be surprised that there are no tokens left - you've just exited a loop who's exit condition was that there must be no tokens left!

As I see it, you have two choices:

1. Store the number of tokens in the StringTokenizer before you start to iterate over them:

Code:

---

  ...
  int size = stok.countTokens();
  while (stok.hasMoreTokens()) {
    System.out.println(stok.nextToken());
  }
  queue qu = new queue(size);

---

2. If you're going to be doing more tokenizing, you can just create a new StringTokenizer object:

Code:

---

  ...
  while (stok.hasMoreTokens()) {
    System.out.println(stok.nextToken());
  }
  stok = new StringTokenizer(string);
  queue qu = new queue(stok.countTokens());
