When using FileWriter or FileOutputStream is there any way to write line returns and/or tab characters?
Thanks

for line return, you can use "\n" but there is a better(platform independant) way.
System.getProperty("line.separator")
I'm sure there is a \something for tab as well, but I dont know it offhand.

From the Java Language Specification:


The character and string escape sequences allow for the representation of some nongraphic characters as well as the single quote, double quote, and backslash
characters in character literals (�3.10.4) and string literals (�3.10.5).
EscapeSequence:
\ b = /* \u0008: backspace BS */
\ t = /* \u0009: horizontal tab HT */
\ n = /* \u000a: linefeed LF */
\ f = /* \u000c: form feed FF */
\ r = /* \u000d: carriage return CR */
\ " = /* \u0022: double quote " */
\ ' = /* \u0027: single quote ' */
\ \ = /* \u005c: backslash \ */

Here's how you write line returns and tabs.
import java.io.*;
public class WriteFile
{
public static void main( String args [] )
{
try
{
FileWriter writer = new FileWriter("file.txt");
writer.write("Hello\tWorld\n");
writer.write("!!!\t!!!");
writer.flush();
writer.close();
}
catch ( Exception ex )
{
ex.printStackTrace();
}
}
}
