What regex pattern would need I to pass to java.lang.String.split() to split a String into an Array of substrings using all whitespace characters (' ', 't', 'n', etc.) as delimiters?

Something in the lines of
myString.split("\s+");
This groups all white spaces as a delimiter.
So if I have the string:
"Hello[space character][tab character]World"
This should yield the strings "Hello" and "World" and omit the empty space between the [space] and the [tab].
As VonC pointed out, the backslash should be escaped, because Java would first try to escape the string to a special character, and send that to be parsed. What you want, is the literal "s", which means, you need to pass "\s". It can get a bit confusing.
The \s is equivalent to [ \t\n\x0B\f\r].
