"\\s" delimiter

When tokenizing a string, what does the "\\s" delimiter refer to? Thank you.

Please show the method and class that you are using that String in.

Actually I was just reading an example. This is the bit of code I was looking at:

Java Code:

String[] result = "this is a test".split("\\s");
     for (int x=0; x<result.length; x++)
         System.out.println(result[x]);

That String must be a regular expression. You need to find the doc for how to write regular expressions.

The \ is a regular expression control character and also a java compiler escape character. To pass a single \ to the regexp you need to escape it for the java compiler: \\
