Performance cost of coding “exception driven development” in Java?

Question

Are there are any performance cost by creating, throwing and catching exceptions in Java?

I am planing to add \'exception driven development\' into a larger project.

Answer 1

There is a performance penalty to throwing an exception, but that's usually acceptable because the exception handling code only executes in exceptional cases. If you start using exceptions for flow control, you're turning the usual case around and making them expected behavior. I'd strongly recommend against it.
