The number of lines in an HTML text box.

[Mohamed Abu Zur]

How can I verify the where the user typed enter (line break) in a
HTML text box within my servlet?
I receive the text data by req.getParameter("field");
But how can calculate the number of lines of text written there?

Thanks in advance

You receive the text into a String, do you not? So you want to find out how
many "lines" of text are in a String. You can use the indexOf() methods of
String to search for any character; in your case you want to search for the
line-end character, which is coded in Java as "\n".
