) throws keyword gives a method flexibility of throwing an Exception rather than handling it. with throws keyword in method
signature a method suggesting its caller to prepare for Exception declared in throws clause, specially in case of checked Exception and provide sufficient handling of them. On the other hand throw keyword transfer control of execution to caller by throwing an instance of Exception. throw keyword can also be used in place of return as shown in below example:
private static boolean shutdown() {
throw new UnsupportedOperationException("Not yet implemented");
}
as in below method shutdown should return boolean but having throw in place compiler understand that this method will always throw exception .
