How To Get OS Version

[Gregg Bolinger]

I am writing an app that uses some commands such as CMD.EXE and COMMAND.COM to do the same tasks. So I need to know which OS version the App is running on to determine which one I need to use. Is there a way to do this?

The only thing I can think of right now is to parse the output of the DOS ver command.

Is that not a similar command such as DIR which I would then need the correct CMD or COMMAND to execute it?
I guess I could try both and find out which one works and use it. Thought maybe there was a more programmable way to do it.

I don't know what I was thinking earlier...

System.out.println(System.getProperties().getProperty("os.name"));
System.out.println(System.getProperties().getProperty("os.version"));
System.out.println(System.getProperties().getProperty("os.arch"));

Ah, you kick butt. Thanks a lot!!
Another question. In the API anywhere does it tell what Strings are allowed in the getProperty() method?
