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:
Create a subclass of Vehicle called Car. Car should have additional attributes of:
make (String)
model (String)
regType (String - values will be either "new" or "renew")
regFee (float)
In addition to the get/set methods for make, model, and regType, include the method calcFee, to calculate the registration fee according to the following conditions:
if regType = renew, then the fee is $36
else if regType = new, then the fee is $58.50

- Write a class named Employee which implements Comparable Interface with name and salary as data fields Add a constructor with argument name and salary. Add getter and Setter for name and salary. Add CompareTo() method for the data Salary. Write a class named Manager which inherits the Employee class. Add an instance variable, named department, of type String. Add a constructor in the subclass class with arguments name, salary, department and a toString() method that prints the manager’s name, department, and salary [Hint: Add a toString( ) method in the super class as well] Create 3 objects of Manager with following arguments 1. (Zayed, 500), 2. ( Ahmed, 700) 3. ( Faisal, 600) Add the above 3 objects into an ArrayLIst object and Sort by Salary and Display. Create an object Employee class with (Zayed, 500,IT) and display the 1. Name 2. Salary 3. Department by using tostring() method.Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() and the equals() methods. The equals() method must return true if the two countries have the same name and same populationSize and false otherwise. The abbreviation is the first letter and the second letter of the country name and must be generated automatically (e.g. if the country name is Palestine the abbreviation is PA, if the country name is Jordan the abbreviation is JO.) Write a main method, define an array of country objects, read countries data from the user, if two countries have the same abbreviation add the last letter from the country name to the abbreviation of the country inserted last. Display countries whose area is greater than 10000 km2.Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.
- Define a class called Country. A Country has population S ize, area, capital, currency, and abbreviation ( (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() method and the equals() method. The equals() method must return true if the two countries have the same name and same area and false otherwise The abbreviation is the first letter and the letter before the last of the country name and must be generated automatically eg if the country name is Palestine the abbreviation is PN, if the country name is Jordan the abbreviation is JA) Write a main method, define an array of country objects, read countries data from the user, if two countries have the same abbreviation add the last letter from the country name to the abbreviation o one million. f the country inserted last Display countries whose populationSize is greater thanAssume B is a subclass of A. Which of the statements about the following assignment is false? A a = new B(); We can assign anything to variable a that has a subtype of B. We can call on a any method defined in A. We can call on a any method defined in B. We can assign anything to variable a that has a subtype of A.Write a class named Employee which implements Comparable Interface with name and salary as data field.

- *using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…Define a java Name class with attributes: String firstname, middle name, lastname.

- Write a class named Person with data attributes for a person’s name, address, and telephonenumber. Next, write a class named Customer that is a subclass of the Person class. TheCustomer class should have a data attribute for a customer number, and a Boolean data attributeindicating whether the customer wishes to be on a mailing list. Demonstrate an instance of theCustomer class in a simple program.The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…PLEASE FAST Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name).

The equals() method must return true if the two countries have the same name and same populationSize and false otherwise. The abbreviation is the first letter and the second letter of the country name and must be generated automatically (e.g. if the country name is Palestine the abbreviation is PA, if the country name is Jordan the abbreviation is JO.)
