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 class Mammal and another class WingedAnimal. Make a class Bat that is derived from both the classes as bat is a mammal as well as a winged animal.
Make constructor of each class and test your classes by making an object of Bat in main function.

- Take the tax program from the last homework assignment and implement it using classes and objects instead. To do so, create a class definition for a class called Customer with attributes income and tax. It should also have a set method for income, and a calcTax() method to assign tax and return it. As a reminder, the tax is calculated as follows: Income Tax Due $0 - $50,000 5% $50,000-$100,000 $2,500 + 10% of (income > $50,000) > $100,000 $7,500 + 15% of (income > $100,000) Create a Customer object in main, have the user enter the income and assign this to the income variable of the Customer object, and then call the calcTax() method for the Customer object and print the tax due.Write the following four classes to practice using an abstract class and polymorphism. Submit all four classes. Shape2D class For this class, include just an abstract method name get2DArea() that returns a double. Rectangle2D class Make this class inherit from the Shape2D class. Have it store a length and a width as fields. Provide a constructor that takes two double arguments and uses them to set the fields. Note, the area of a rectangle is the length times the width. Rectangle2D class Also make this class inherit from the Shape2D class. Have it store a radius as a field. Provide a constructor that takes a double argument and uses it to set the field. Note, the area of a circle is PI times it's radius times it's radius. Shape2DDriver class Have this class provide a method named displayName() that takes an object from just any of the above three classes (you can't use an Object type parameter). Have the method display the area of the object, rounded to one decimal place. using JAVA…Create a deck of cards class. Internally, the deck of cards should use another class, a card class. Your requirements are: The Deck class should have a deal method to deal a single card from the deck After a card is dealt, it is removed from the deck. There should be a shuffle method which makes sure the deck of cards has all 52 cards and then rearranges them randomly. The Card class should have a suit (Hearts, Diamonds, Clubs, Spades) and a value (A,2,3,4,5,6,7,8,9,10,J,Q,K)
- 1. Design a new Triangle class that extends the abstract GeometricObject class. Draw the UML diagram for the classes Triangle and GeometricObject then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides, and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.using java programmingDefine a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…Write a shoe class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "nikes, adidas", "puma") price (e.g., 100, 200,60) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230
- Inheritance and PolymorphismThis assignment starts with the Account class from Labs 4 and 5.Our new and improved bank has two kinds of accounts, savings, and checking. In addition to an ID and a balance, savings accounts have an annual interest rate and a minimum balance. Checking accounts have a minimum balance and a monthly fee. Withdrawals and deposits can be made to both kinds of accounts. At the end of each month, savings accounts pay interest, but only if the account’s balance is above the minimum. Also at the end of each month,a fee is deducted from each checking account, but the fee is waived if the account’s balance is over the minimum. Tasks1.Create a complete UML diagram which shows the relationships between the three classes, Account, Savings, and Checkingand all of the fields and methods in each. The only modificationsrequired to the Account class is the addition of two abstract methodscalled closeMonth and accountString.2.The closeMonth function performs the appropriate…Complete the code for the following program. You are provided with an abstract class called abst. Create a class that will be a child of abst and it will be called usesAbst. Your program will have an int variable called value, and all the appropriate methods, as well 2 constructors. The first constructor will simply set the variable value to 0. The second constructor will set the variable value to equal a passed in parameter. You do not have to comment your code. public abstract class abst{ public abst () { } //Outputs to the screen the message Hello public abstract void sayHello (); //returns the stored int value public abstract int getValue (); //sets the int value to x public abstract void setValue (int x); //Outputs to the screen the message Another method public void output () { System.out.println("Another method"); public String tostring () { return "This is an abstract class"; }Deeper Class Design - the Square Class In this section, your job will be to write a new class that will adhere to the methods and data outlined in the “members” section below (said another way, your classes will implement a specific set of functions (called an interface) that we’ll describe contractually, ahead of time). These classes will all be shapes, with actions (methods) that are appropriate to shape objects, such as “getArea()”, or “draw()”. First we build a Square class that contains the following data and methods listed below, and then later, we will copy it to quickly make a Circle class. Note: when considering each data item below, think about what type of data would best represent the concept we’re trying to model in our software. For example, all shapes will have a coordinate pair indicating their location in a Cartesian coordinate system. This x and y pair may be modeled as ints or floats, and you might choose between the two depending on what the client application will…
- Use the Animal class file given on the final exam module. Use Inheritance and Polymorphism concepts to create the following classes and functions. Create the following classes that derive from the Animal class. Monkey Kangaroo Create a derived class named Spider Monkey whose base class is Monkey. Create constructors for each class. Create destructors for each class. All classes will have the following private instance fields, including Animal legs that will initialize to 0 boolean swim that will initialize to false; All classes will have the following polymorphic methods, including Animal getLegs( ) – this returns the number of legs the animal has makeSount( ) – this outputs the type of sound the animal makes makeSound( ) method will be a virtual function in the Animal class Create an exception in the getLegs( ) method that makes sure the number of legs are valid (only allow positive number amount of legs) Create a main method to demonstrate the all functions including the…Problem: Create a base class called Vehicle that has the manufacturer’s name (type String), number of cylinders in the engine (type int), and the owner (type Person). Use the Person class developed this semester. Create a class automobile that is derived from Vehicle and has additional properties: number of passengers (type int) and weight in tons (type double). Create a class Truck which is derived from Vehicle and has additional properties: the load capacity in tons (type double, since it may contain a fractional part) and towing capacity in tons (type double). The classes should have: Two constructors, a default and an overloaded constructor All appropriate accessor and mutator methods (getters and setters). An ‘equals’ method (must conform to the Person example and the Object class ). A ‘toString’ method A ‘copy’ constructor A ‘clone’ method A ‘finalize’ method Write a driver (client/test) class that tests ALL the methods. Be sure to invoke each of the constructors, and ALL…Having a separate destructor for each class seems unnecessary.
