Coffee Machine Simulator

This is a Coffee Machine Simulator implemented in Java, designed to manage a virtual coffee machine with various features. The simulator allows users to interact with the coffee machine through a REPL (Read, Eval, Print, Loop) console application.

Features

1. Buy Coffee: Users can select different types of coffee and purchase them. Each coffee type has a specific price and requires certain amounts of ingredients.
   The coffee types available are:
   

   • Espresso:

     • Price: $4/cup
     • Water needed: 250 ml/cup
     • Milk needed: 0 ml/cup
     • Coffee beans needed: 16 beans/cup

   • Latte:

     • Price: $7/cup
     • Water needed: 350 ml/cup
     • Milk needed: 75 ml/cup
     • Coffee beans needed: 20 beans/cup

   • Cappuccino:

     • Price: $6/cup
     • Water needed: 200 ml/cup
     • Milk needed: 100 ml/cup
     • Coffee beans needed: 12 beans/cup

   The coffee machine will dispense the selected coffee only if it contains sufficient ingredients. Otherwise, an error message will be displayed.

2. Fill Ingredients: The simulator provides an option to add ingredients to the coffee machine. Users can specify the amounts of water, milk, and coffee beans to be added.

3. Take Money: The maintainer can use the "take" option to retrieve the money stored in the coffee machine's money box.

4. Show Ingredients: Users can check the current levels of ingredients available in the coffee machine.

5. Exit: The "exit" option stops the simulation and terminates the program.

Extension

The simulator includes an additional option called "Analytics" that provides useful information about the coffee machine's operations. The "Analytics" option displays the following:

• Total count of each type of coffee sold.
• Total amount of money earned.
• Total amounts of ingredients consumed.
