  • The easiest way is on OS level, just redirect stdout to a file when you start the process. – Henry Feb 01 '15 at 05:27

Yes, it's possible to redirect stdout on DOS or any *nix type Operating System.

java -jar somefile.jar > my_file.txt

If you're using a *nix system you can also use the tee command (which will output to the stdout and to a file) like

java -jar somefile.jar | tee my_file.txt

Both also support appending to the file

java -jar somefile.jar >> my_file.txt

or

java -jar somefile.jar | tee -a my_file.txt

There are plenty of ways to achieve this, the easiest one is while running through command prompt 

java class_name >file_name.txt

It would be great if you can provide more details on this.
