Split on string giving false result

Question

I have a string a follows

String caret= "Y^LEAD_PROJECT_V.vw^View LEAD_PROJECT_V.vw^INF^View^Extension^RECOMPILE^Unit Test^Recompile - Test ^Test View PROJECT_V.vw^^SIMPLE^^^^^^^";

I want to split this string with ^. So I used the following code to split it

String[] split = caret.split("\\^");
System.out.println(split.length);

split.length obtained :

split.length required:

19 // as there are 18 caret symbols in the string

I don't understand what am I doing wrong in it. Whatever regex I use, I'm getting the same result. Also I cannot modify the string caret.

Can anyone please help me in getting 19 as array length.

Split does not keep empty strings. See [this answer](http://stackoverflow.com/a/13939902/2006429) to keep empty strings. — rgajrawala, Feb 10 '16 at 07:55

Try to use "\\^",-1 like this:

  String[] split = caret.split("\\^",-1);

With using -1 you can include empty string, having an output = 19.

Can you explain what the `-1` means? – rgajrawala Feb 10 '16 at 07:56
