Line breaks are encoded by special characters that are different to a regular space. Usually, they are represented by "\n", whereas a whitespace is just " ". So for your usecase, a command like

modifiedString = originalString.replace("\n","")

will do the trick. It replaces all newlines by a 0-length string, thus removing it.

If you want to dive deep into the topic, it will also be interesting to look into the differences of "\r" and "\n".
