Inheritance Encapsulation Polymorphism None of the above Answer: You cannot create an object using a/an: superclass constructor subclass constructor ancestor class constructor abstract class constructor Write a complete Java program that prompts the user for a series of numbers to determine the smallest value entered. Before the program terminates, display the smallest value Write Java code that uses a do... while loop that prints even numbers from 2 through 10. 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. Write a Java method that takes an integer array as a formal parameter and returns the sum of integers contained within the array. Declare and create a 10 times 10 multidimensional array of doubles. What is the output of the following code? Declare and create a 10 times 10 multidimensional array of doubles. What is the output of the following code? ini[] numbers = new int[10]; for(int i=0; i
