Line feed is char 0x000A and Carriage Return is char 0x000D to add these to your StringBuffer simply use append(char) so.... StringBuffer sb = new StringBuffer("Hello"); sb.append(0x000A); // for line feed sb.append(0x000D); //for carrage return Now in java, there are two escape characters for these line feed = '\n' carriage return '\r' And so it becomes sb.append('\n'); sb.append('\r'); if you wish to have both, sb.append("\n\r");
ALl the above is true, but please be careful with this. If you are generating a file to be stored on the system and read by other software it is strongly recommended that you add the appropriate end-of-line characters for the platform you are running on. Unix systems use just a linefeed (\n), Dos and Windows use carriage return land inefeed (\r\n), Others use just a carraige return, or lifefeed then carriage return ... Luckily Java provides System.getProperty("line.separator") which gives you a String containing the appropriate end-of-line sequence, so you can just do: <pre> StringBuffer sb = new StringBuffer("Hello"); sb.append(System.getProperty("line.separator")); </pre> which will then work on any platform. This is an important part of making your program "100% Pure Java"
