What are the effects of exceptions on performance in Java?

Question

Question: Is exception handling in Java actually slow?

Conventional wisdom, as well as a lot of Google results, says that exceptional logic shouldn\'t be used for n

Answer 1

Why should exceptions be any slower than normal returns?

As long as you don't print the stacktrace to the terminal, save it into a file or something similar, the catch-block doesn't do any more work than other code-blocks. So, I can't imagine why "throw new my_cool_error()" should be that slow.

Good question and I'm looking forward to further information on this topic!
