Answer:
import java.util.Scanner;
public class Supermarket
{
public static void main (String[] args)
{
String item;
double pounds, ounces, price,
total, unit;
Scanner scn = new Scanner(System.in);
System.out.print("Please enter the name of item ");
item = scn.nextLine();
System.out.print("Please enter the price of " + "the item per pound : ");
price = scn.nextDouble();
System.out.print("Enter the weight of " + "the item in pounds and " + "ounces respectively : ");
pounds = scn.nextDouble();
ounces = scn.nextDouble();
unit = price/16;
total = price * (pounds + ounces/16);
System.out.print("The unit price of " + "the products sold is : " + unit);
System.out.print("\nThe total cost of the " + "amount purchased is : " + total);
}
}
Explanation:
- Ask the user to enter the price of the item and the weight.
- Calculate the unit and the total price.
- Display the unit and the total price.
Answer:
//Import the Scanner class to allow for user's input
import java.util.Scanner;
//Create the class declaration
public class SuperMarket {
//Write the main method
public static void main(String[] args) {
//Create an object of the Scanner class
//to read in user's input
Scanner input = new Scanner(System.in);
//Declare all variables with their correct types
String ItemName;
double Pounds, Ounces, PoundPrice, TotalPrice, UnitPrice;
//Prompt the user to enter all details one after the other
//Receive the inputs and store in the right variables
System.out.println("Please enter the item name");
ItemName = input.nextLine();
System.out.println("Please enter the price of the item per pound");
PoundPrice = input.nextDouble();
System.out.println("Please enter the weight of the item in pounds");
Pounds = input.nextDouble();
System.out.println("Please enter the weight of the item in ounces");
Ounces = input.nextDouble();
//Calculate the unit price using the given formula
UnitPrice = PoundPrice / 16;
//Calculate the total price using the given formula
TotalPrice = PoundPrice * (Pounds + Ounces / 16);
//Print out the results as follows;
System.out.println("Item Name : " + ItemName);
System.out.println("Unit Price : " + UnitPrice);
System.out.println("Total Price : " + TotalPrice);
} //End of main method
} //End of class declaration
