🚘Parking Management System

A console-based Parking Management System developed using Java. The application allows users to manage vehicle parking records efficiently through a menu-driven interface.

Features

• Park a vehicle
• Remove a parked vehicle
• View all parked vehicles
• Search vehicle by number
• Show total parked vehicles
• View available parking slots
• Display parking summary
• Remove all vehicles
• Generate parking receipts on vehicle exit
• Append daily report entries for each removed vehicle
• Input validation and exception handling

Technologies Used

• Java
• Object-Oriented Programming (OOP)
• Collections Framework
• Exception Handling

Project Structure

• Main.java — menu-driven user interface
• ParkingManager.java — parking operations and business logic
• Vehicle.java — base vehicle class with entry time and slot details
• TwoWheeler.java — two-wheeler parking fee calculation
• FourWheeler.java — four-wheeler parking fee calculation

How It Works

The application manages parking in two categories:

• Two-Wheelers: slots A1 to A5
• Four-Wheelers: slots B1 to B5

When a vehicle is parked, it is stored in memory with its entry time and assigned slot. When a vehicle is removed, the system calculates parking duration, fees, and saves a receipt.

Exit and Input Handling

The menu accepts a choice between 1 and 9. Choosing 9 exits the program cleanly and closes the scanner resource.

Receipt Details

When a vehicle is removed, the application generates a receipt file named:

• receipt_<vehicleNumber>.txt

Example for vehicle number GJ-03-CP-0301:

========== PARKING RECEIPT ==========
Vehicle Number : GJ-03-CP-0301
Owner Name     : John Doe
Vehicle Type   : 4-Wheeler
Slot Number    : B2

Entry Time     : 09-06-2026 14:25:12
Exit Time      : 09-06-2026 16:30:05
Duration       : 2 Hours

Total Fee      : Rs40
====================================

The receipt includes:

• Vehicle number
• Owner name
• Vehicle type
• Assigned slot
• Entry time
• Exit time
• Duration in hours
• Total fee

Daily Report

Each removed vehicle also writes an entry to daily_report.txt in append mode. One line is added for every removal, for example:

GJ-03-CP-0301 | 4-Wheeler | Rs40 | 2 Hours

This file accumulates the day's transaction summary for review.
