Is it possible to use I/O redirection in Eclipse?
I want to redirect standard input/output on the command line like java MyProgram <input.txt >output.txt, but I can't seem to get it to work in Eclipse. I tried including the <'s as part of the program arguments, which was ignored, and also in the VM arguments, which just threw up a class not found error. How can I do this?
You can redirect output using the Run dialog, Common tab, "Standard Input and Output" section.
However, it doesn't look like you can redirect input as far as I can tell (and as far as this Stack Overflow question can tell, too).
How much control do you have over your application? If you don't mind a bit of a hack, you could have a couple of properties or command line arguments to determine the appropriate files, and use System.setOut and System.setIn accordingly. It is a bit of a hack though...
