Java-Login-Attendance-Manager

This repository contains my first Java project where I have cloned an existing Login, User Management, and Attendance System application for Abumatics. It is built using Java Swing for the desktop application interface and MySQL for managing the database.

The project allows users to:

• Register, view, update, and delete user details.
• Mark attendance twice a day and calculate the total duration for attendance.
• Generate and view QR codes for users.

Project Details

Overview

This is a Java Swing-based desktop application designed to manage user registrations, attendance, and QR code generation. The application allows administrators to:

• Register new users by entering details such as name, gender, email, and uploading their photo.
• View a list of registered users.
• Update user details like name, gender, and email.
• Delete users from the system.
• Generate unique QR codes for each user.
• Mark attendance twice a day and calculate the total duration of the user's attendance.
• View attendance records.

Components of the Project

1. Login Page

The login page is the entry point of the application. Users are required to enter a predefined username (azhar) and password (azhar) to access the system.

• Once logged in, users can access all the functionalities such as user registration, attendance marking, and QR code generation.

2. User Registration Form

Admins can register new users by entering their details such as:

• Name
• Gender
• Email
• Photo upload

Once the details are entered, the user is added to the database.

3. View Registered Users

After users are registered, administrators can view all registered users in a list. From this page, they can:

• View user details.
• Update user information.
• Delete users.

4. Update User Details

Admins can modify an existing user’s details such as:

• Name
• Email
• Gender
• Photo

Changes are then reflected in the database after clicking the "Update" button.

5. Delete User

If a user needs to be removed from the system, the admin can select the user and click the "Delete" button. This removes the user from both the GUI and the database.

6. QR Code Generation

Once a user is registered, an admin can generate a unique QR code for that user. The QR code contains user-specific data that can be scanned by QR code readers.

7. Mark Attendance

Admins can mark attendance twice a day for each user:

• The first attendance is recorded when the user arrives.
• The second attendance is recorded when the user leaves.
• The system calculates the total time spent in the system by subtracting the arrival time from the departure time.

Attendance Calculation:

For each day, the total attendance duration is calculated as:

attendanceDuration = departureTime - arrivalTime;

Screenshot:

8. View Attendance

Admins can view the attendance records for all users, including:

• Arrival Time
• Departure Time
• Total Duration of Attendance

How the Database is Managed

• Database Configuration:
  The database will be automatically created when you run the application. All the tables for users, attendance, and QR codes will be set up during the first run.
  You only need to change the database URL and password in the Java code to match your MySQL credentials.

  Update the DB URL and password in the Database.java (or similar) file:

  String dbUrl = "jdbc:mysql://localhost:3306/yourDatabaseName";
  String dbUser = "yourMySQLUsername";
  String dbPassword = "yourMySQLPassword";

• DAO (Data Access Object):
  The DAO layer interacts with the MySQL database, handling operations like inserting new users, updating user details, and marking attendance. The application performs CRUD operations to manage the user data efficiently.

---

Technologies Used:

• Java 23: The backend programming language used to build the logic of the application.
• Java Swing: Used for creating the graphical user interface (GUI), allowing for drag-and-drop components.
• MySQL: The relational database management system to store user data, attendance, and QR codes.
• DAO (Data Access Object): Used to manage the interaction between Java and MySQL databases for performing CRUD operations.

How to Install and Run:

1. Clone this repository:

   git clone https://github.com/yourusername/Java-Login-Attendance-Manager.git

2. Set up the MySQL Database:
   • The application will automatically create the necessary tables when you run the program.
   • You only need to update the database URL and password in the Java code to match your MySQL credentials:

     String dbUrl = "jdbc:mysql://localhost:3306/yourDatabaseName";
     String dbUser = "yourMySQLUsername";
     String dbPassword = "yourMySQLPassword";

3. Run the Application:
   • Open the project in NetBeans or any Java IDE.
   • Compile and run the Login.java file to start the application.
4. Login: Use the predefined username and password (azhar / azhar) to access the system.

Future Enhancements:

• Add email validation during user registration.
• Implement password recovery feature.
• Allow bulk attendance marking through CSV upload.
