Question

You are going to write a java application that will be used in a coffee shop to take customer orders and print a simple on screen order summary. Your coffee shop only sells one type and one size coffee for $5 dollars. However, your customers have the option of adding whipped cream and chocolate each for $1 dollar.

Your application takes in customer name, the number of coffees being ordered and whether or not the customer wants whipped cream and/or chocolate on them. It provides a live update of the total price based on customer order and once the order is placed it will provide the customer with an order summary.

Answer 1

CoffeePay.java

import java.util.Scanner;

public class CoffeePay {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter the customer name: ");

String name = scan.next();

System.out.println("Enter the number of coffees being ordered: ");

int n = scan.nextInt();

boolean cream[] = new boolean[n];

boolean chocolate[] = new boolean[n];

int total = 0;

for(int i=0;i<n;i++){

total = total + 5;

System.out.println("Enter create to be added to the coffee "+(i+1)+": ");

cream[i] = scan.nextBoolean();

if(cream[i]) {

total = total + 1;

}

System.out.println("Enter chocolate to be added to the coffee "+(i+1)+": ");

chocolate[i] = scan.nextBoolean();

if(chocolate[i]) {

total = total + 1;

}

System.out.println("Total Price: "+total);

}

int price = 0;

System.out.println("\tCustomer "+name+" Summary");

System.out.println("Order\t\tCream\tChocolate\tPrice");

for(int i=0; i<n;i++) {

price = 5;

if(cream[i]) price++;

if(chocolate[i]) price++;

System.out.printf("%s %10s %10s %10s\n","Coffee"+(i+1),cream[i],chocolate[i],price );

}

System.out.println("Total Price: "+total);

}

}
