This would work in windows2000:

C:\>java filename > filename.txt

else use java.io package. Check this url: http://www.javacoffeebreak.com/java103/java103.html

While using the redirect method, if you expect Exceptions (and you should) you might add something like the following code to your main:

PrintStream _holdErr = System.err;
System.setErr(System.out);

Of course if your original question was more like how do you write data to a file (vs System.out.println() calls) see:

Hope this helps,
James
