Hi ranchers
Sorry for the incompleted question in the previous forum. Below is the completed question

  
  Which of the following statements is not true? 
a.  An interface that is declared within the body of a class or interface is known as a nested interface. 
b.  A constant can be a member of an interface. 
c.  A class declaration can be a member of an interface. 
d.  A class that implements an interface must implement all of the methods declared within the interface. 
e.  None of the above. 

The answer for the above code is d.
But i thought the answers are b,d . Can anyone explain why b is not a correct answer. I read that constant can be a member of an interface.

Thanks
kalpana

Hi
A constant can be a member of an interface
A variable declared within an interface is implicity public static and final which implies that it is a constant, therefore the answer.
