7. Which of the following is true about inheritance? Inheritance allows a child instance to access properties from a parent instance. Inheritance allows a parent class to extend the expected behavior of a child class Inheritance refers to when classes receive the properties and methods of their parent class. Inheritance is used to instantiate a clone of a parent object. 8. When would you use a static method over an instance method? When the method's return value is immutable When the class is declared as a static class When overriding an inherited method from a parent class When the method acts on the entire class, not just one object instance

Java - If the programmer doesn't declare any constructors for an extended class, what constructors will be inherited from the superclass? How does this inherited constructor initialize new instance variables that are not part of the superclass?
When the inheritance is private, then the private members/methods of parent class are in the child class. Select one: a.public b.protected c.inaccessible d.private
Multiple inheritance can be explained as all choices are wrong one class inheriting from more super classes more classes inheriting from more super classes one class inheriting from more super classes and more classes inheriting from one super class more classes inheriting from one super class
Question 30 Which of the following description is TRUE? Inheritance allows us to define a class based on another class. Child classes receive all the features from the parent class but can NOT have their own additional features. Abstraction means that a method in a parent class can have a number of different implementations in child classes. An interface is a completely abstract class, which contains abstract properties, methods, and variables. The private access modifier makes members accessible only from within the class and hides them from the outside.
:Single inheritance means one class inheriting from one super classes more classes inheriting from one super class more classes inheriting from more super classes None of the above
How are instances of a given class's objects made if the class in question does not include a method called Object(), which is referred to as "native code"?
Polymorphism : Write a driver program that uses a AECar reference variable to point to three different types of classes, showing that inheritance is one mechanism for using polymorphism.
Class Relationships Exercises 1. In Java, we use inheritance for "is-a" relationships. Containment, on the other hand, indicates that one object has another object. These are "has-a" relationships. For the following relationships, determine if they are a "is-a" or a "has-a" relationship: o bicycle - vehicle o car - engine o pizza - topping o food - pizza o dog - mammal 2. Share with someone else 3 other examples for each of the following relationships: o Inheritance ("is-a" relationship) o Containment ("has-a" relationship) 3. public class PersonInfo { protected String firstName; protected String birthdate; } public class ChildInfo extends PersonInfo { private String schoolName; } public class MotherInfo extends PersonInfo { private String spousename; private ChildInfo children1; private ChildInfo children2; private ChildInfo children3; ... } A. Draw the relationships for the classes above using UML. If a class inherits from another class, draw an open arrow pointing to the base class…
