Is there an online sandbox environment for compiling and running java?

In case available computer does not have java installed it might help to have some sort of a web app that allows to try out code in a browser.
I think this might be useful for learning Java.
Perhaps something along these lines: http://codepad.org/

Yes, there is; please search. Somebody posted a link to such an environment which they had developed, about two months ago, but I can't remember where. I tried it and found errors in its behaviour with Exceptions.

Is this the one you were refering to?

Yes, I think it was. I tried something which I expected would throw an Exception, possibly an ArrayIndexOutOfBoundsException because there were no command-line arguments, and did not suffer the expected Exception. I can't seem to find the old thread, however.

Thank you very much.

Thank you, Ulf. That old thread does indeed show where I got the wrong Exception.

Hi! browxy URL changed to http://www.browxy.com. There is a new beta version where you can run interactive programs (like the ones that use Scanner). Also run applets, save, edit and also publish your code to a public url
