Question

This is JAVA. Must write a short description of this program, usually a sentence or two will be sufficient. All the classes, methods and data fields should be clearly documented (commented).

Write a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county sales tax. Assume the state sales tax is 4 percent and the county sales tax is 2 percent. The program should display the amount of the purchase, the state sales tax, the county sales tax, the total sales tax, and the total of the sale (which is the sum of the amount of purchase plus the total sales tax).

Hint: Use the value 0.02 to represent 2 percent, and 0.04 to represent 4 percent.

Example Run

Enter the purchase amount: 30.8
Purchase amount: $30.8
State tax: $1.232
County tax: $0.616
Total tax: $1.8479999999999999
Total cost: $32.648

Answer 1

CODE

import java.util.Scanner;

/**

* Java code to calculate the total purchase cost of a product which includes state sales tax of 4% and county sales tax of 2%.

*/

public class Main {

/*

* main method which asks the user for the purchase cost of an item and finds the total cost including the taxes.

*/

public static void main(String[] args) {

double purchaseAmount; // field to store the user input for the purchase price of the item

Scanner sc = new Scanner(System.in);

System.out.println("Enter the purchase amount: ");

purchaseAmount = sc.nextDouble();

double stateTax = 0.04 * purchaseAmount; // calculate the state tax

double countyTax = 0.02 * purchaseAmount; // calculate the county tax

System.out.println("Purchase amount: $" + purchaseAmount);

System.out.println("State tax: $" + stateTax);

System.out.println("County tax: $" + countyTax);

System.out.println("Total tax: $" + (stateTax + countyTax));

System.out.println("Total cost: $" + (purchaseAmount + stateTax + countyTax));

}

}
