Find and replace all NewLine or BreakLine characters with \n in a String - Platform independent

Question

I am looking for a proper and robust way to find and replace all newline or breakline chars from a String independent of any OS platfo

Answer 1

This seems to work well:

String s = "This is a String\nand all newline chars\nshould be replaced in this example.";
System.out.println(s);
System.out.println(s.replaceAll("[\\n\\r]+", "\\\\n"));

By the way, you don't need to catch exception.
