🥤 Vending Machine (Java)

A console-based Vending Machine simulation built using Core Java. This project models real-world vending machine behavior including product selection, payment validation, and purchase handling.

🚀 Features

• 🛒 Multiple product support (dynamic product list)
• 🔍 Product search based on user input
• 💰 Money insertion & validation
• 📦 Product availability check
• 💳 Purchase processing
• 💸 Remaining balance returned to user
• ⚙️ Clean and modular structure

---

🧠 How It Works

1. User inserts money

2. User enters product name

3. System searches through all available products

4. If product is found:

   • Checks if sufficient balance is available
   • Deducts product price
   • Dispenses product
   • Returns remaining balance

5. If not found → shows error
