Unable to remove white space in String

Question

I'm trying to remove white space in a String, adressString (see below).

To do so, I'm using the folowing piece of code :

adressString.replaceAll("\r","");

However, this does not work : I'm stil having this whitespace (see below) :

Solution :

I needed to declare another String :

String adressWithoutCarriageReturn = adressString.replaceAll("\r", "");

Just add one more slash like below:

adressString.replaceAll("\\r","");

As "\" is a special character.
