About Question enthuware.ocpjp.v7.2.1627 :

[sinapse]

"It has three constructors - StringTokenizer(): Default delimiters, delimiters not returned as tokens StringTokenizer(String str, String delim): custom delimiters, delimiters not returned as tokens. StringTokenizer(String str, String delim, boolean returnDelims): custom delimiters, delimiters returned as tokens if returnDelims is true."

And after you create a StringTokenizer with:

StringTokenizer st = new StringTokenizer("this is a test");

[sinapse]

StringTokenizer(String str)
Constructs a string tokenizer for the specified string.
