replace \n and \r\n with in java

Question

This has been asked several times for several languages but I can\'t get it to work. I have a string like this

String str = \"This is a string.\\nThis is a l         


        

Answer 1

This should work. You need to put in two slashes

str = str.replaceAll("(\\r\\n|\\n)", "
");

In this Reference, there is an example which shows

private final String REGEX = "\\d"; // a single digit

I have used two slashes in many of my projects and it seems to work fine!
