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]
.
