AP Computer Science A Unit 9 Progress Check: MCQ Consider the following class declarations. public class Dog { private String name; public Dog() { name = "NoName"; } } public class Poodle extends Dog { private String size; public Poodle(String s) { size = s; } } The following statement appears in a method in another class. Poodle myDog = new Poodle("toy"); Which of the following best describes the result of executing the statement? - -B. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". An implicit call to the no-argument Dog constructor is made, initializing the instance variable name to "NoName". Consider the following class declarations. public class Publication { private String title; public Publication() { title = "Generic"; } public Publication(String t) { title = t; } } public class Book extends Publication { public Book() { super(); } public Book(String t) { super(t); } } The following code segment appears in a method in another class. Book myBook = new Book("Adventure Story"); // Line 1 Book yourBook = new Book(); // Line 2 Which of the following best describes the result of executing the code segment? - -C. Object myBook is created using the one-argument Book constructor, which uses super to set myBook's title attribute to "Adventure Story".
