1Throws statement is used at the end of method signature to indicate that
2an exception of a given type may be thrown from the method.
3The main purpose of throws keyword is to delegate responsibility of
4exception handling to the caller methods, in the case of checked exception.
5In the case of unchecked exceptions, it is not required to use throws keyword.
6We can use throws keyword only for throwable types otherwise compile time error
7saying incompatible types.
8An error is unchecked, it is not required to handle by try catch or by throws.

14The method should throw only checked exceptions and subclasses
15of checked exceptions. It is not recommended to specify exception
16superclasses in the throws class when the actual exceptions thrown in
17the method are instances of their subclass.
