Chapter 16.4, Problem 16.11CP

In the following Rectangle class declaration, the width, length, and area members are of type double. Rewrite the class as a template that will accept any numeric type for these members.

class Rectangle

{

private:

double width:

double length;

double area;

public:

void setData(double w, double l)

{ width = w; length =l;}

void calcArea()

{ area = width * length; }

double getWidth()

{ return width; }

double getLengthQ

{ return length; }

double getArea()

{ return area; }

Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1)      The test program, the ComparableDog class, and its super class Animal are given as follows.     // Main method   public static void main(String[] args) {     // Create two comparable Dogs     ComparableDog dog1 = new ComparableDog(3);     ComparableDog dog2 = new ComparableDog(4);          System.out.println("Dog1:" + dog1);     System.out.println("Dog2:" + dog2);               if(dog1.compareTo(dog2) == 1)               System.out.println("Dog1 is older than Dog2");        else if(dog1.compareTo(dog2) == -1)               System.out.println("Dog1 is younger than Dog2");        else               System.out.println("Dog1 and Dog2 have the same age");      }…
