Sure, because output.txt is a text file.
Once it has been created it is a text file like any other.

File redirection is a feature of the operating system's command line interface, not a feature of Java. File redirection can be used with any program that writes to the monitor. For example, the DOS command DIR writes a summary of the files in a directory to the monitor:
C:\temp>dir
Volume in drive C is DISK4_VOL1
Volume Serial Number is 1C25-5670
Directory of C:\temp
01/09/2006 07:29p <DIR> .
01/09/2006 07:29p <DIR> ..
01/09/2006 07:29p 115 Hello.java
1 File(s) 115 bytes
2 Dir(s) 30,987,882,496 bytes free
C:\temp>
You can send the same characters to a file by doing this:
C:\temp>dir > dirlist.txt
You can type out the contents of the new file by doing this:
C:\temp>type dirlist.txt
The same characters as the first DIR command wrote will
be written out.
Similar commands work for Unix or for Max OS X.
(Use cat instead of type, and
use ls instead of dir.
If there already is a file named stuff.txt, what happens if you do:
C:\temp>java myProgram > stuff.txt
