Coffee Machine project in Java.
From JetBrains Academy (hyperskill.org).
About
What can be better than a cup of coffee during a break?
A coffee that you don’t have to make yourself.
It’s enough to press a couple of buttons on the machine
and you get a cup of energy; but first, we should teach
the machine how to do it. In this project, you will work
on programming a coffee machine simulator.
The machine works with typical products: coffee, milk, sugar,
and plastic cups; if it runs out of something,
it shows a notification. You can get three types of coffee:
espresso, cappuccino and latte. Since nothing’s for free,
it also collects the money.
Thoughts
Project evolves through six stages, starting
with just printing out the steps of making a coffee,
through adding in water, milk, beans fields,
finally ending with a full-fledged coffee machine that
can be re-filled and money taken out of.
Last stage involves designing a state machine using enums.
Overall, a good project to work through.
