Quick Lemonade

A simple Java console application for managing lemonade orders (single-file project).

What it does

• Place new lemonade orders
• View orders by status (Preparing / Delivered / Canceled)
• Search orders by Order ID
• Search customers and list their orders
• Update order quantity or status
• Show best customers (by total value)

Files

• Lemonade.java — main source file (console app)

Prerequisites

• Java JDK 8 or later installed and javac/java available on PATH

Build & Run

From the project directory (Windows cmd / PowerShell / Linux shell):

javac Lemonade.java
java Lemonade

Quick Usage

• Follow on-screen prompts.
• Customer IDs expected as 10-digit phone numbers (e.g. 0770000001).
• Prices are shown as plain doubles; the default lemonade price is set inside the source.

Known issues & notes

• Input reading uses Scanner.next() and nextInt() directly; entering unexpected data may throw exceptions.
• The code uses labeled loops (L1, L2, ...) and raw arrays — this works but can be hard to maintain.
