The code compiles cleanly and shows "Object Version".
The code compiles cleanly and shows "String Version"
The code throws an Exception at Runtime.
the ans is 3rd.
i thought if the code were written like 'questin.method("null")', the ans were 3rd, but .... i dont know why?

In method overloading compiler looks for the most specific method in selection.Here null can be easily passed to String version.
However it can pass to Object versions too but its not more specific than Strings version.
