Is the a App for the iPhone that lets you use Java?

I recently got a Jailbroken and modded iPod Touch for free and I was wondering if there are any Apps that let you use Java. I know that the iPhone doesn’t support Java but Im sure there has to be at least something that would let you emulate it or something.

Like I sad its Jailbroken and modded so violating the terms of agreement doesnt mean anything to me.
