thanks in advance.

use processbuilder. makes easy redirect output of command file shown below:

new processbuilder("echo", "hello").redirectoutput(new file("output.txt")).start(); 

if want append output file:

new processbuilder("echo", "hello").redirectoutput(redirect.appendto(new file("output.txt"))).start();
