Answer 4

That is a "try block" used to catch runtime errors and exceptions.
When an error occurs it might return an exception number. if its exception number 3 or 4, then that value would be passed to catch like a normal method, take the place of x, and then execute the block as written. in this case it would print itself to the console. If no runtime error occurs then this is all skipped and the code continues.
