There are cases when handling errors in applications is acceptable, but such cases are rare.An application should not handle exceptions that can result in an unexpected or exploitable state. If you cannot predict all possible causes of an exception and ensure that malicious code cannot exploit the resulting application state, you should allow the application to terminate instead of handling the exception.Do not exclude any special exceptions when catching for the purpose of transferring exceptions.Instead of creating lists of special exceptions in your catch clau

Exception handling uses the try, catch, and finally keywords to try actions that may not succeed, to handle failures when you decide that it is reasonable to do so, and to clean up resources afterward.
