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.

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_forward
- JAVA - USING CONSTRUCTORS Create a class named House that includes data fields for the number of occupants and the annual income as well as methods named setOccupants(), setIncome(), getOccupants() and getIncome() that set and return those values respectively. Additionally, create a constructor that requires no arguments and automatically sets the occupants field to 1 and income field to 0. Create an additional overloaded constructor . This constructor receives an integer argument and assigns the value to the occupants field. Create a third overloaded constructor this time, the constructor receives 2 arguments, the values of which are assigned to the occupants and income fields respectively. Create another class named I_house that instantiates the House class and see if the constructors work correctly.arrow_forwardObjective: At the end of the activity, the students should be able to: Apply method overloading in a program.
