Answer / ritesh
Whenever we want to force an exception then we use throw keyword.Moreover throw keyword can also be used to pass a custom message to the exception handling module i.e. the message which we want to be printed.
Whereas when we know that a particular exception may be thrown or to pass a possible exception then we use throws keyword

Answer / basant
) 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 .

Answer / ritesh
Throw :- It is possible for your program to throw an
exception explicitly, using the throw statement.
Throws :- If a method is capable of causing an exception
that it does not handle, it must specify this behavior so
that callers of the method can guard themselves against that
exception.
