Question

Write a program that when run, produces a menu showing beer brands and their prices and then prompts the user enter his/her choice (1,2,3 or 4). The user is then asked how many bottles he/she wants. He is then given the total cost (depending on the cost of the beer chosen) as the output. See sample dialog below. If he/she enters an invalid choice e.g. 8, he/she should get an error message.

Answer 1

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    System.out.println("1. Kingfisher - 3.28$");
    System.out.println("2. Heineken - 2.12$");
    System.out.println("3. Carlsberg - 4.30$");
    System.out.println("4. Corona - 1.57$");
    System.out.println();
    System.out.println("Choose the bear: Type number:");

    int choice = Integer.parseInt(scanner.nextLine());
    double pricePerBottle = 0.0;

    switch (choice){
        case 1: pricePerBottle = 3.28;
        break;
        case 2: pricePerBottle = 2.12;
        break;
        case 3: pricePerBottle = 4.30;
        break;
        case 4: pricePerBottle = 1.57;
        break;
        default:
            System.out.println("Wrong input. Type number 1 - 4");
    }
    if (pricePerBottle != 0.0) {
        System.out.println("Input number of bottles:");
        int amount = Integer.parseInt(scanner.nextLine());

        System.out.println("The total cost is " + amount * pricePerBottle);
    }
