How to split string in Java on whitespace?

Question

How do I split a string with any whitespace chars as delimiters?

Yes, I tried to search it on google and stackoverflow, but no good results. I have a string, lets say: "Lets do some coding in Java" and I would like to got strings (split it on whitespaces):

Lets, do, some, coding, in, Java

I used string.split("\\s") for this, but know I need to use regex instead. Any ideas?

`"\\s"` is a Regex for a single whitespace character, see the [Pattern class](http://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html) — jlordo, Nov 21 '12 at 15:27
Using google with "java regex split" gives you all the information you need.., — oopbase, Nov 21 '12 at 15:27
If you see the documentation of `String.split()`, it takes Regex as parameter only to split. — Rohit Jain, Nov 21 '12 at 15:27
`String.split()` takes a regexp as parameter so your question doesn't make sense. — Aaron Digulla, Nov 21 '12 at 15:27
Did you even look at the JavaDocs for split http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/String.html#split(java.lang.String). It cleary says that it takes a regex. — Craig Suchanec, Nov 21 '12 at 15:29

to specify space as splitting char, you can pass " " as parameter to String#split. Example:

String test="Lets do some coding in Java";
    for(String token : test.split(" "))
        System.out.println(token);

Better to use `\\s+` for splitting on any number of spaces. – Rohit Jain Nov 21 '12 at 15:31

it won't work it has multiple space.String s ="hello sorry". – sunleo Nov 21 '12 at 15:32
It has one space, my code would split "hello sorry" in "hello" and "sorry" (try). It won't handle the case in which the test phrase has multiple spaces, as @RohitJain pointed out. Your solution is better than mine because is more general. – avalori Nov 21 '12 at 15:52
