What does regular expression \\s*,\\s* do?

Question

I am wondering what this line of code does to a url that is contained in a String called surl?

String[] stokens = surl.split(\"\\\\s*,\\\\s*\");

<

Answer 1

That regex "\\s*,\\s*" means:

• \s* any number of whitespace characters
• a comma
• \s* any number of whitespace characters

which will split on commas and consume any spaces either side
