Robocode Problem

When I try to open the robocode.bat file, the console opens and then immediately closes. I took a screenshot of the console and it reads

"[file path]>java -Xmx512M -cp libs/robocode.jar robocode.Robocode %*

'java' is not recognized as an internal or external command, operable program or batch file."

Any ideas? Thanks.

I should have made it more clear in the OP that I'm not able to use Robocode at all now.

Assuming Java is installed, this would be the step you're missing: Robocode/System_Requirements#PATH_must_be_set

It worked! Thanks.

Huh. It seems my Robot Editor no longer has a built-in codesize checker. Did this change with the update, or could I have another missing classpath somewhere?

Nevermind, I'm using Voidious's command line trick from here now, so it doesn't matter.
