Java Question

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

What regex pattern would need I to pass to the

method to split a String into an Array of substrings using all whitespace characters (' ', '\t', '\n', etc.) as delimiters?


Something in the lines of


This groups all white spaces as a delimiter.

So if I have the string:


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]
