Coffee Machine
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.
Learning outcomes
This project allows to get a taste of Java. Practice working with classes, challenge yourself with loops and conditions, and get more confident in Java.
Result will look like
STAGE 1 “HELLO, COFFEE
A program that puts basic information on the screen: give the machine a chance to tell the customers what it’s doing!
STAGE 2 “MACHINES HAVE NEED”
Program the machine to calculate the amount of ingredients it needs depending on how many people want some coffee.
STAGE 3 “ENOUGH COFFEE FOR EVERYONE”
Working with conditions, program the machine to estimate how many creamy coffees it can make based on the amount of ingredients we enter.
STAGE 4 “ACTION!”
set the machine to perform three basic actions: collect the money, renew the supplies, and serve the coffee.
STAGE 5 “ON A COFFEE LOOP”
Program the machine to display on the screen the amount of supplies left. Set the main loop: now the menu keeps updating until you enter “exit”.
STAGE 6 “BRUSH UP THE CODE”
Time for some final touch-ups: structure the code so that it runs smoothly. Using enums
