At the end of the activity, the students should be able to:
Apply method overloading in a program.
Procedure:
1. Develop a simple program for an individual savings account. Create two (2) classes named
AmountDue (no class modifier) and RunAmountDue (public).
2. For the AmountDue class, create three (3) overloaded methods named computeAmountDue based
on the following conditions:
• With a single parameter: It represents the price of one (1) item ordered. Add 12% tax and
return the total due.
With two (2) parameters: These represent the price of an item and the quantity ordered.
Multiply the two (2) values, add 12% tax, and return the total due.
With three (3) parameters: These represent the price of an item, the quantity ordered, and
the discount amount. Multiply the quantity and price, deduct the discount amount, add 12%
tax, and return the total due.
3. For the RunAmountDue class, import the Scanner class to be able to use the nextDouble()
method.
4. Instantiate an AmountDue object…
Java - Constructors
Create a class named Book that has the following attributes:
Publisher - String Year Published - Integer Price - Double Title - String
Create a constructor for the class Book that has the parameters from the attributes of the class. After, create a method for the class that displays all attributes. Ask the user for inputs for the attributes and use the constructor to create the object. Lastly, print the values of the attributes.
Inputs
1. Publisher

- In Java Programming, 2 class needs a no-arg constructor and a constructor that initializes all fields with data (The ProductionWorker class constructor should receive data for the Employee class fields as well). I need help to create a method within the Employee and ProductionWorker classes called displayInfo. (displayInfo accepts no arguments and returns void). To display the data for each constructor, the demonstration class will call the subclass displayInfo method and it will call the superclass displayInfo method. User input is not required for the demonstration class. Have a class named "Employee" with the following fields: - Employee Name - Employee Number in format XXX-L, X = digit w/ range 0-9 & L = letter w/ range A-M. - Hire Date Then one or more constructors and the appropriate accessor and mutator methods for the class. Also, another class named "ProductionWorker" that extends "Employee" class. The "ProductionWorker" class should have the following fields to hold…arrow_forwardWrite a program named SalespersonDemo that instantiates objects using classes named Real EstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each objects data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salespersons full name—the first and last names separated by a space. Then perform the following Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field. Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use. In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalespersons total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.arrow_forward1.
