OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- When a concrete class inherits from an abstract class, you have to implement all abstract methods declared in the super class before you can instantiate it (the concrete class). True FalseQUESTION 16 What must be true of a class with one abstract method? O The class must also implement the Iterable interface Any derived class must implement the method The abstract method must have the static modifier O The method cannot specify a return value QUESTION 17 Suppose we wanted to design a set of classes for a veterinarian's office. Our Customer class looks like this: public class Customer { Pet [] pets; } Select all the statements that are true Once the size of the pets array has been set, it cannot be changed Because we're using an array, all pets must be the same A customer must have at least one pet We also need to declare a Pet class QUESTION 18 What is the proper use of an enumeration? To define a set of ordered values To enforce the use of the Comparable interface O To define, or enumerate, the values returned by a Random object generator O To define the classes in an inheritance hierarchypublic class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. Implement setters for day, month, and year. Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.
- Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat.

This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food .

Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class.
