what is difference between throw and throws in exception?

Answer

throw : throw is used to throw exception by user whenever he
feels to throw exceptions. throw is used to throw
either user defined or runtime exception.
for ex : throw new MyException(), here MyException
is user written exception.
throw new NullPointerException(), here
NullPointerException is RuntimeException.

throws: throws is used by the method to throw exception to
the calling method. And method itself does not able
to handle it so it throws to calling method.
