public StrTokeniser(String str, String delim, boolean returnTokens)
delim
argument are the delimiters
for separating tokens.
If the returnTokens
flag is true
, then
the delimiter characters are also returned as tokens. Each
delimiter is returned as a string of length one. If the flag is
false
, the delimiter characters are skipped and only
serve as separators between tokens.
