- Why is it important for a class to have a destructor implemented? With your comment, fill in the spaces.Create a deck of cards class. Internally, the deck of cards should use another class, a card class. Your requirements are: The Deck class should have a deal method to deal a single card from the deck After a card is dealt, it is removed from the deck. There should be a shuffle method which makes sure the deck of cards has all 52 cards and then rearranges them randomly. The Card class should have a suit (Hearts, Diamonds, Clubs, Spades) and a value (A,2,3,4,5,6,7,8,9,10,J,Q,K)You cannot instantiate an interface but you can do so to an abstract class. True False

What can the child do to make the methods 'usable' for itself?Why is it better to give this information into a method rather than directly into the object of the active class, and what are the advantages associated with doing so?
- 16. Create a class SubstitutionCipher that implements the interface MessageEncoder, as described in the previous exercise. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. (Hint: You may wish to define a private method that shifts a single character.)Search for textbooks, step-by-step expl = bartleby e Q&A Library Design a class nam Start your trial Design a class named MyPoint to represent a point with X-and y-coordinates. The class contains: The data fields x and y that represent the coordinates with getter methods. A no-arg constructor that creates a point (0, 0). A constructor that constructs a point with specified coordinates. A method named distance that returns the distance from this point to a specified point of the MyPoint type. A method named distance that returns the distance from this point to another point with specified x- and y-coordinates. A static method named distance that returns the distance from two MyPoint objects. Draw the UML diagram for the class then implement the class. Write a test program that creates the two points (0, 0) and (10, 30.5) and displays the distance between them.

RobotFriend is a new toy just on the market. Copy the starter class and the tester from Codecheck. A RobotFriend has a name and replies to various commands Provide a constructor that takes the name of the RobotFriend as a parameter. Remember that a constructor has the same name as the class. What does the class need to remember? That is the instance variable. Provide the following methods: public String getName () gets the name of this RobotFriend • public void setName (String newName) sets a new name for this RobotFriend • public String whatDoYouNeed () returns a string consisting of name + needs a battery charge" where name is the name of this RobotFriend (which was supplied in the constructor) public String doCommand (String whatToDo) returns a string consisting of "Your friend " + name + does not + whatToDo where name is the name of this RobotFriend and whatToDo is the parameter
