An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions. an exception should not result in total failure, but instead be attended by an exception handler.Exception handling is a built-in construct in many programming languages.Usually, exceptions are handled by unwinding the stack, thus rolling back to a defined state outside the exception's scope, and then invoking a handler block or routine.
