To build this Java project, we created a framework that takes input from the user for student name, subject, total classes, and classes attended. After entering the details, when the user hits the submit button, all the details will be saved permanently in the database.<\/p>\n<iframe loading=\"lazy\"  id=\"_ytid_89463\"  width=\"1080\" height=\"607\"  data-origwidth=\"1080\" data-origheight=\"607\" src=\"https:\/\/www.youtube.com\/embed\/eB9VnMT0HJk?enablejsapi=1&autoplay=0&cc_load_policy=0&cc_lang_pref=&iv_load_policy=1&loop=0&rel=1&fs=1&playsinline=0&autohide=2&theme=dark&color=red&controls=1&\" class=\"__youtube_prefs__  no-lazyload\" title=\"YouTube player\"  allow=\"fullscreen; accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen data-no-lazy=\"1\" data-skipgform_ajax_framebjll=\"\"><\/iframe>\n<h2><span style=\"font-size: 26px;\">I<\/span><span style=\"font-size: 26px;\">ntroduction<\/span><\/h2>\n<p>Our attendance management system offers functionality to input, update, and display student attendance records for various subjects. Built with JDBC (Java Database Connectivity), the system interfaces seamlessly with a MySQL database hosted locally to store and retrieve attendance data. To make the project more interactive for its users, we have used the Swing module to implement the GUI.<\/p>\n<p>Our main interface includes input fields for a student&#8217;s name, the total classes held, and the number of classes the student attended. Users can select a subject (like PHYSICS, CHEMISTRY, or MATHS)\u00a0via a dropdown. There are dedicated buttons to either add new records or update existing ones. Moreover, a table view offers a comprehensive look at all the stored attendance records, and users can click on a table row to quickly populate the input fields for potential updates.<\/p>\n<h2>Objectives<\/h2>\n<p><span data-preserver-spaces=\"true\">Here are the objectives for building the Attendance Management System Java Project:<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">1. Digital Attendance Tracking<\/span><\/strong><span data-preserver-spaces=\"true\">: Transition from traditional manual methods of tracking attendance (like registers or sheets) to a digital platform, ensuring data accuracy and ease of access.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">2. Data Storage and Retrieval<\/span><\/strong><span data-preserver-spaces=\"true\">: Implement a system that reliably stores student attendance records in a local MySQL database and displays\u00a0all the attendance records in a tabulated format, offering users an overview of data and facilitating quick edits by simply clicking on a specific row.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">3. User-Friendly Interface<\/span><\/strong><span data-preserver-spaces=\"true\">: Develop an intuitive GUI using Java&#8217;s Swing framework, allowing users to input and view attendance data seamlessly.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">4. Versatile Subject Handling<\/span><\/strong><span data-preserver-spaces=\"true\">: Enable the tracking of student attendance across multiple subjects, such as PHYSICS, CHEMISTRY, and MATHS.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">5. Data Validation<\/span><\/strong><span data-preserver-spaces=\"true\">: Ensure that necessary fields, such as a student&#8217;s name and total classes, are filled in before data is stored to prevent incomplete or inaccurate records.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">6. Real-Time Attendance Percentage Calculation<\/span><\/strong><span data-preserver-spaces=\"true\">: Automatically compute the percentage of classes attended by a student based on the input data, assisting in the analysis of attendance trends or determining eligibility criteria that depend on attendance percentages.<\/span><\/p>\n<h2>Requirements<\/h2>\n<p><strong>Development Environment:<\/strong><\/p>\n<ul>\n<li><strong>Operating System:<\/strong> With enough processing power and memory to run a Java application and a MySQL server.<\/li>\n<li><strong>Java Development Kit (JDK)<\/strong>: You must have the JDK installed to compile and run Java applications.<\/li>\n<li><strong>Integrated Development Environment (IDE)<\/strong>: An IDE such as <a href=\"https:\/\/www.jetbrains.com\/idea\/\">IntelliJ IDEA<\/a> or <a href=\"https:\/\/www.eclipse.org\/downloads\/\">Eclipse<\/a> to facilitate coding, debugging, and project management.<\/li>\n<\/ul>\n<p><strong>Database:<\/strong><\/p>\n<ul>\n<li><strong>MySQL Database Server<\/strong>: The system uses a MySQL database to store and retrieve attendance records.<\/li>\n<li><strong>MySQL JDBC Driver<\/strong>: This is a Java library that enables the application to interact with the MySQL database.

data-preserver-spaces=\"true\">1. Main<\/span><\/strong><span data-preserver-spaces=\"true\"><strong>:<\/strong> This is the entry point for the application. When run, it instantiates an Attendance object which brings up the GUI.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">2. Attendance<\/span><\/strong><span data-preserver-spaces=\"true\"><strong>:<\/strong> This class handles the GUI and database operations related to attendance management.<\/span><\/p>\n<h3><strong><span data-preserver-spaces=\"true\">Key Components<\/span><\/strong><\/h3>\n<p><strong><span data-preserver-spaces=\"true\">1. JFrame &amp; Components<\/span><\/strong><span data-preserver-spaces=\"true\">: The GUI is built using Swing components. It consists of JTextFields to input the student&#8217;s name, the total classes held, and the number of classes attended. A JComboBox is used to select the subject (PHYSICS, CHEMISTRY, or MATHS). There&#8217;s also a JTable to display attendance records and two buttons for adding and updating records.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">2. Database Connection<\/span><\/strong><span data-preserver-spaces=\"true\">: The code uses the JDBC (Java Database Connectivity) API to connect to a MySQL database. It assumes the database is hosted locally (jdbc:mysql:\/\/localhost:3306\/intern), and the username and password are both root.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">3. Adding Records<\/span><\/strong><span data-preserver-spaces=\"true\">: When the &#8220;ADD RECORD&#8221; button is clicked, the program attempts to insert a new record into the attendance table in the database. Before doing so, it calculates the percentage attendance and then adds this, along with other details, to the table.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">4. Updating Records<\/span><\/strong><span data-preserver-spaces=\"true\">: When the &#8220;UPDATE RECORD&#8221; button is clicked, the program updates the attendance details of a specific student for a given subject in the attendance table. The subject to update is determined by the selected item in the JComboBox.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">5. Displaying Records<\/span><\/strong><span data-preserver-spaces=\"true\">: The JTable is populated by fetching data from the attendance table in the database. The function buildTableModel converts the ResultSet from the SQL query into a table model suitable for displaying in a JTable.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">6. Click Event on JTable<\/span><\/strong><span data-preserver-spaces=\"true\">: When a row in the JTable is clicked, the respective student&#8217;s details are fetched and displayed in the JTextFields for further operations (like updating).<\/span><\/p>\n<h3><strong>Graphical User Interface(GUI)<\/strong><\/h3>\n<p>1. Our GUI consists of 3 textfields, a combo Box, &amp; a Jtable<\/p>\n<p>2.\u00a0 Two buttons, \u201c<strong><em>Add Record<\/em><\/strong>\u201d &amp; \u201c<strong><em>Update
