This Car Rental System is a Java-based application that allows customers to search for available cars, make reservations, modify and cancel existing reservations, and view their reservation history. Additionally, it provides admin functionalities such as managing cars, customers, and generating reports on car usage and revenue.

Prerequisites

• Java Development Kit (JDK) 8 or higher.
• Java IDE (Eclipse, IntelliJ, etc.).
• MySQL database server.

Database Configuration

1. Set up your MySQL database server.
2. Create a new database named cars using the following SQL command:

sql -> (CREATE DATABASE cars;)

3. Ensure that the database server is running.
