• Loops
• Conditional statements
• Switch expressions
• Scanner for user input
• Input validation
• Dynamic array creation based on user input
• Return values from methods
• Breaking a larger program into smaller methods

How It Works

1. The program welcomes the user and asks how many coffee orders they want to place.
2. Based on the number of orders entered, the program creates arrays of the required size to store the details of each order.
3. For each order, the user selects the coffee type, coffee size, quantity, whipped cream, and whether to add a flavor shot.
4. If a flavor shot is selected, the user chooses between Vanilla and Hazelnut.
5. The program calculates the price of each order based on the selected coffee, size, add-ons, flavor, and quantity.
6. The selected coffee, size, quantity, and calculated price are displayed for the order.
7. After all orders are entered, the program generates a final receipt containing the details and price of each order.
8. The total bill for all orders is calculated and displayed at the end.

1. Clone this repository.
2. Open the project in IntelliJ IDEA or any Java-compatible IDE.
