CRLF into java string

Question

I've coded a string in Java where I inserted a LF (linefeed) at the end like this:

String str = "......\n"; 

Now I need to need newline made of a Carriage Return and a Line Feed, a CRLF. In hex that is 0D 0A instead of 0A. Is there a way to insert this into my string?

Answer 1

Use \r\n:

String str = "......\r\n"; 

From the JLS:

\n    /* \u000a: linefeed LF */ \r    /* \u000d: carriage return CR */ 

Answer 2

Perhaps the simplest way is to use constant strings. I've taken this from my own ASCII class which defines all 33 non printable codes as their ASCII name, e.g.

public final static char CR  = (char) 0x0D; public final static char LF  = (char) 0x0A;   public final static String CRLF  = "" + CR + LF;     // "" forces conversion to string  String twoLines = "Line1" + CRLF + "Line2";   // 12 characters
