ANSWER ONLY NO. 8 AND EXPLAIN Create a constructor named Exam that assigns "Good luck" to a previously declared String variable named message. Create an empty overloaded constructor for the Exam class with two (2) String parameters named period and level. Declare a double-type accessor named getPrice that returns the value of price. Declare a boolean-type accessor named isFinished that returns the value of status. Declare a class named Midterm that inherits from the class named Exam. Create three (3) class declarations to show multiple levels of inheritance. Use the classes named Exam, Midterm, and Essay. Create a constructor named Midterm that prints "Exam has started." using println(). Its first statement should be a call to a constructor in the parent class. Given the base class named Quiz and the derived class named Essay, write a statement to show inheritance between these classes.
