Question

Prompt 1 Write a program for a simple vending machine. The vending machine contains the following set of drinks (indexed from 1 to 5): Coca-Cola, Sprite, Snapple, Dr. Pepper, Water. A variable byte choice will simulate user input (suppose a user is able to input a number < byte's max size). Your program must output the following: "You have chosen %s" where %s is a placeholder for the name of the drink choser. Prompt 2: Write a program that checks whether a given int integerToCheck is even or odd and positive or negative, or none of those (take 0 to not be odd or even, for whatever reason).

Answer 1

                Scanner scan = new Scanner(System.in);
                System.out.println("1: Coca-Cola");             //Different drinks available in the machine
                System.out.println("2: Sprite");
                System.out.println("3: Snapple");
                System.out.println("4: Dr. Pepper");
                System.out.println("5: Water");

                case 5:
                        System.out.println("You have chosen Water.");
                        break;
                default:
                        System.out.println("Please enter a valid choice.");
                        break;
                }
        }
