Try a StreamTokenizer instead.

If you need to use a StringTokenizer then use:
StringTokenizer token = new StringTokenizer(string);

and then use Integer.parseInt() to check if each token is a number or not.

String a = "2d 1 3d 1 animation 1 curve 1 graphic 1";
    StringTokenizer token = new StringTokenizer(a);
    while(token.hasMoreTokens())
      {
        try{
          int i = Integer.parseInt(token.nextToken());

Just to confirm, does the string have space between the two words/characters, i.e "2d 1 3d 1".

If yes, we can use the space " " as a delimiter?
just a basic workaround

String l_Str = "2d 1 3d 1 animation 1 curve 1 graphic 1";

StringTokenizer l_Tok = new StringTokenizer(l_Str, " ");
while (l_Tok.hasMoreElements()) {
      String l_Elem = (String)l_Tok.nextElement();

      if(l_Elem.length()>1) {
            System.out.println(l_Elem);
      }
}

you can't print out the value using that code, instead try:

String s = "2d 1 3d 1 animation 1 curve 1 graphic 1";
StringTokenizer i = new StringTokenizer(s);
while (i.hasMoreTokens())
{
    try
    {
          String token = i.nextToken();
          int n = Integer.parseInt(token);
          System.out.println(""+n);
    }
    catch (Exception e)
    {
        System.out.println("String  " + token);
    }
}
