Length of String

[Mr. X.]

Hello.

What function resolves the length of a string ?
(I have tried String.length, strlen, ... but didn't find any).

Thanks

I think at this point, you need to just learn Java.

The answer is String.length(), but this is so basic, you shouldn't
asking questions like that here.

Non-static operations are sometimes written like this:
»String#length()«.

»String.length()« looks like a static operation.

Yup, I was unclear (and incorrect).

String s = new String();
s.length();

is called on the object, not the class. Possibly the OP knew what I
meant, but that was potentially a very confusing mistake I made.

It is one of the elementary Java Gotchas.

See http://mindprod.com/jgloss/gotchas.html

s.length() when s is a string
a.length when a is an array
c.size() when c is a collection

This sort of thing is explained in every Java text. You need at least
one, possibly out of date, text to explain the basics of the syntax.
