Can multiple catch blocks be executed for a single try statement?

For a single try statement, there can be multiple catches, but most often, there will only be one catch block that stops the entire thing from being seen. The idea with the catches and the reasoning behind having multiple is very simple. You want to be able to stop problems before they arise. If you point out specific issues you could see happening and want the program to stop being executed if they arise, you program them in as a catch. If the problem is encountered, the program stops. The biggest piece of advice given here is to give specific catches before less specific catches.

You would want to block the specific try-catch models from the user because this could be potentially disastrous if the user is a hacker.
