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

It works for me.

public class Program
{
    public static void main(String[] args) {
        String str = "This is a string.\nThis is a long string.";
        str = str.replaceAll("(\r\n|\n)", "
");
        System.out.println(str);
    }
}

Result:

This is a string.
This is a long string.

Your problem is somewhere else.
