New to Java

Hello
I post this in jsp but I think this one is more suitable:

I have a Form that allows user to fill in. In that form, I have an address field (textarea).

Now I want to know the length of this address. I uses

String size = addressField.length();

The size is correct if I have only one line in the address. But if I enter an adress with multi-line, the size is much more than what I count (by hand) even I add one value for each line.

For example, if address "Wellington" has one line as:

Wellington

It can be seen that the size is: 10

But if I enter this in multi lines:

W
e
ll
ing
ton

It can be seen that, by counting, the size is 14 (10+4=14)

However, I get the value of addressField.length() is 18

How I should get value for only 14

Many thanks
