Splitting a string on space except for single space

Question

I was splitting a string on white spaces using the following

myString.split("\\s+");

How do i provide exception for single space. i.e split on space except for single space

Answer 1

Like this:

myString.split("\\s{2,}");

or like this,

myString.split(" \\s+"); // notice the blank at the beginning.

It depends on what you really want, which is not clear by reading the question.

You can check the quantifier syntax in the Pattern class.

Answer 2

You can use a pattern like

myString.split("\\s\\s+");

This only matches if a whitespace character is followed by further whitespace charactes.

Please note that a whitespace character is more than a simple blank.
