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");
}…
A class Student can have three member variables: name, age, and an array of grades of two exams marks [5]. The grades can be integers (0-100), doubles (0.0-100.00) and characters (A-F, where F denotes grades less than 50). Write a class template to accommodate all five types of grades. The class template must have two constructors (no-arg constructor, and aconstructor that takes 7 parameters: name, age and grades of 5 exams). Write a c++ function to read an object from console, and another function to print the object to the console. Implement the class template by creating three objects with three different types (int, double and char) of grades, and printing the objects on the console.
