Question

In Java please:

Answer 1

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 2

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

===========================================================

Sample Output:

>> Please enter the item name

Biscuit

>> Please enter the price of the item per pound

780

>> Please enter the weight of the item in pounds

67

>> Please enter the weight of the item in ounces

90

>> Item Name : Biscuit

>> Unit Price : 48.75

>> Total Price : 56647.5
