Chapter 3, Problem 2.1E

Explanation of Solution

Constructor:

  • It is the collection of statements that is executed at the time of object creation so as to initialize the object’s state.
  • The compiler when declaring the object for the class automatically calls the constructor functions.
  • Constructor creates and initializes objects that do not even exist yet.
  • Constructors are called implicitly.
  • Constructor name should be same as class name...

Explanation of Solution

Initializing object’s instance variables:

When a class has only the default constructor, its instance variables are initialized to their default values...

(a)Definition of class Vehicle Instance variables: year                 that holds the year of vehicle (int) make               that holds the make of vehicle (string)   Methods: a second constructor that accepts the Vehicle's year and the make as arguments. These values should be assigned to the object's instance variables: year and make.  Accessor methods (getYear() and getMake()) that get the values of instance variables Mutator methods (setYear(int) and setMake(String)) that set the values of instance variables. toString() should return a string with the values of instance variables of vehicle object  equals() should accept a vehicle object reference as argument and return true if all instance variables of calling object are same values as those of passed vehicle object, respectively, or false otherwise.   brake() should do nothing (i.e., empty body). This method is for polymorphism to call appropriate brake() method of subclass.   (b)Definition of class Car, which is a…
