8. Write an interface called Exam with a method Pass(int mark) that returns a Boolean. Write another interface called Classify with a method Division(int average) which returns a string. Write a class called Result which implements both Exam and Classify. The pass method should return true if the marks is greater than or equal to 35 else false. The division method must return “First” when the parameter average is 60 or more, “second” when average is 50 or more but below 60, “no division” when average is less than 50.
