because at compile time the compiler knows only about the Hotel class.....compiler thinks you would call Hotel's method whch declares to throw a checked exception....which shoudl be caught....which isnt in your code....so bang ...compile error

clear hai?

Ankur is right, you have to handle exception at main by either declaring it or catching it
