Answer / ravivarman
Throw keyword can be used by a program to throw exceptions
explicitly.the execution of the current block stops
immediately after the throw statement.
A method should declare that it can cause an exception and
expects its caller handle or re-throw the exception.

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 / chandrakala
throw and throws are clauses.
throws: if we are not interested to catch the exception then we have to use throws. if any exception arises then internally JVM handles that exception.
throw: If we want to throw an exception explicitly we have to use throw.It comes under user defined exception.

Answer / ravikumar
Throws - what ever the exception you are declaring are
taken care by JVM. If it is a user defined exception in throws
block, JVM doesn't know when to throw that exception . For
this purpose we use Throw for a certain conditions/logic to
throw these user defined exceptions
