Create a Dog and a Cat class, each of which inherit from Animal. Each class should have a constructor which initialses their name and a hello method. The cat's hello method should return the string "Meow" and the dog's hello method should return the string "Woof". The Animal class is public abstract class Animal { public Animal(String n) name = n; } abstract String hello(); public String greeting() { return hello() + ", I am " + name; } // private private String name; } Your classes will be used in the following Main class. public class Main { public static void main(String () args) { Animal cat = new Cat("Angel"); Animal dog = new Dog("Fido"); System.out.println(cat.greeting()); System.out.println(dog.greeting()); } Note that your Cat and Dog classes must not supply a greeting method. They should use the greeting method from the Animal class.

1. Define a Class: Circle Circle - radius: double + Circle() +Circle(double r) +setradius(double r): void +getradius() : double +calculateArea(): double +calculateCircumference: double 2. Use a Circle instance (object) in a main() method Program.
Consider the following class Date, which represents a date using three ints for month, day and year: class Date { private: int month; int day; int year; public: Date() { month = day = year = 0; } Date(int m, int d, int y) { month = m; day = d; year = y; } bool operator==(Date); bool operator<(Date); }; Write an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not. You may assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You do not need to demonstrate calling these operators.

The weight of an object can be described by two integers: pounds and ounces (where 16 ounces equals one pound). Class model is as follows: public class Weight { private int pounds; private int ounces; public Weight(int p, int o) ( pounds=p+o/16: ounces = 0% 16: } Implement a method called subtract, which subtracts one weight to another. i.e. Weight w1 = new Weight(10.5): Weight w2 = new Weight(5.7): Weight w3= w1.subtract(w2):
