Question

Write a program in a class SandwichCounter that computes the cost of sandwiches sold at a food stand. Three kinds of sandwiches —cheese steak, chicken, and salad— are cost, respectively, $8.5, $7.5, and $7.0 per sandwich. Create an array of strings that holds the names of these sandwiches. Create another array that holds the cost of each corresponding sandwich. Your program should read the name of a sandwich and the quantity desired by a customer. Locate the sandwich in the name array and use that index to find the cost per purchase in the cost array. Compute and print the total cost of the sale.

Answer 1

import java.util.Scanner;

public class SandwichCounter {
   public static void main(String[] args) {
       String names[] = { "cheese steak", "chicken", "salad" };
       double prices[] = { 8.5, 7.5, 7 };
       //reading name and quantity
       System.out.println("Enter the name of the sandwich cheese (steak, chicken,salad)");
       Scanner sc = new Scanner(System.in);
       String n = sc.nextLine();
       System.out.println("Enter quantity");
       int q = sc.nextInt();
       double total = 0;
       //iterating through loop to fing the cost for entered sandwich
       for (int i = 0; i < names.length; i++) {
           if (n.equalsIgnoreCase(names[i])) {
               // finding total cost
               total = q * prices[i];
               break;
           }
       }
       System.out.println("Total Cost :$" + total);
   }
}
