Java Regex - Using String's replaceAll method to replace newlines

Question

I have a string and would like to simply replace all of the newlines in it with the string " --linebreak-- ".

Would it be enough to just write:

string = string.replaceAll("
", " --linebreak-- ");

I'm confused with the regex part of it. Do I need two slashes for the newline? Is this good enough?

Answer 1

Don't use regex!. You only need a plain-text match to replace " ".

Use replace() to replace a literal string with another:

string = string.replace("
", " --linebreak-- ");

Note that replace() still replaces all occurrences, as does replaceAll() - the difference is that replaceAll() uses regex to search.
