Write a method called power the computes x^n where x and n and positive integers. The method has two integer parameters and returns a value of type long. Create a class named Appointment that contains instance variables startTime, endTime, dayOfWeek (valid values arc Sunday through Saturday), and a date which consists of a month, day and year. All times should be in military time, therefore it is appropriate to use integers to represent the time. Create the appropriate accessor and mutator methods. Create a Java class named Book with instance variables title, author, ISBN, and yearPublished. Include javadoc style comments to describe your interface. Such a class would normally have methods, but you are not required to supply any methods. Add accessor and mutator methods to the Book class created in question #13. Add a constructor and a copy constructor to the Book class created in question #13
