From The Java Language Specification:

21.10.2 public StringTokenizer(String str, String delim)

This constructor initializes a newly created StringTokenizer so that it will recognize tokens within the given string str. All characters in the string delim will be considered delimiters. Delimiter characters themselves will not be treated as tokens.

http://java.sun.com/docs/books/jls/first_edition/html/javautil.doc10.html#7648

So if String s = "aa||bb||cc||d|d||ee";
String delim = "abcde";
StringTokenizer tok = new StringTokenizer(s, delim);
Only "||" and "|" returned.
if tok = new StringTokenizer(s, delim, true);
Everything is returned because delimiter characters themselves are treated as tokens.
