@@@@@@@Payable Interface:

• Create an interface called Payable
• Payable will include
• An enum, PayType, with the values CASH, CARD, PHONE
• Two methods:
• getPayType() which takes no arguments and returns a PayType
• setPayType(PayType) which takes a single PayType argument and returns void

@@@@@Order class will be updated as follows:

• Order class will implement the Payable interface
• Include an additional attribute, payMethond, of type PayType
• Set payMethod to PayType.CASH in the default constructor
• Include two simple methods for getPayType() and setPayType(PayType)
• Add a line to the bottom of the receipt via the toString() method that shows the payment type as shown in the Example Run

DessertShop class will be updated as follows:

• Include an additional attribute, paymentMethond, of type String
• After all items have been added to the order and before printing the receipt:
• Ask the user what form of payment will be used. Use input validation to only accept valid types, as shown in the Example Run.

BIG HINTS for DessertShop updates:

• Use enum.values() to get a list of all possible values in the enum. This is helpful to run through all enum values in a FOR-loop-for(Payable.PayType type : Payable.PayType.values())
• Use enumValue.name() to get a String version of the ENUM value
• if (paymentMethod.equals(type.name()))
• Use a switch statement to switch on the validated user input and set the order PayType
