Question

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 computeAmount Due 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 RunAmount Due class, import the Scanner class to be able to use the nextDouble() method. 4. Instantiate an AmountDue object named due in the main method to use the three (3) overloaded methods you have created earlier. When the program runs, the user can input 1-3 values separated by spaces, then the amount due will be displayed.

Objective:
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 named due in the main method to use the three (3) overloaded
methods you have created earlier. When the program runs, the user can input 1-3 values separated
by spaces, then the amount due will be displayed.
Sample Output:
Press any of the following then enter values separated by spaces:
1 - Price only
2 - Price and quantity
3 - Price, quantity, and discount amount
