Next iteration - Extra hot.

The machine has been upgraded and the drink maker is now able to make orange juice and to deliver extra hot drinks. You have to update your code to send the correct messages to the drink maker so that users can have orange juices or extra hot drinks.

Let us see if your implementation is flexible enough to welcome those changes with not too much hassle.

Use cases

trikitrok

Next iteration - Going into business.

The coffee machine is not free anymore! One tea is 0,4 euro, a coffee is 0,6 euro, a chocolate is 0,5 euro.

The drink maker will now only make a drink if enough money is given for it.

Use cases

• The drink maker should make the drinks only if the correct amount of money is given.
• If not enough money is provided, we want to send a message to the drink maker. The message should contains at least the amount of money missing.
