How to force fail a java regex?

Question

In java, you can text a regex by doing

"mystring".matches("myregex")

But is there a certain regex you can use, that will make matches function evaluate to a false? It needs to work for all cases (i.e. no matter what string you test it with).

Thanks.

I don't know why you would need this, but this should do the trick

"mystring".matches("(?!)")
