Good morning.
I want to send split to a String such as " abc def " and receive
back an Array with the two elements String(abc) and String(def); and I want
to receive back a zero-length Array if the target is empty or contains only
white space.
The following code produces an unwanted empty string as the first element.
This also occurs when the target is a zero-length String or a String
composed only of spaces.
After all morning, I can't find the solution. Thanks for any help, Ron.
" abc def ".split("\\s+")
=> Array("", "abc", "def")
" ".split("\\s+")
=> Array("")

Have you looked at the StringTokenizer class?
Yes, I've looked at it; but it's been deprecated in favor of split.

Why don't you trim(), before you split() ?

Hey... I learned something new today. I hadn't realized it had been
deprecated...
StringTokenizer is not listed in the deprecated API for the 1.4.2 version
of the JSDK.
I know.. But if you read the API for 1.4.2, it says: http://java.sun.com/j2se/1.4.2/docs/...Tokenizer.html
StringTokenizer is a legacy class that is retained for compatibility
reasons although its use is discouraged in new code. It is recommended
that anyone seeking this functionality use the split method of String
or the java.util.regex package instead.
--- END QUOTE --
Note, that this does not appear in the 1.4.1 docs. Maybe its just prep
for them deprecating in 1.5... This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
