Our application helps colleges and institutions keep track of students and their related information. <\/span><span data-preserver-spaces=\"true\">The program opens up a window on your screen. In that window, you can type in a student&#8217;s information, such as their ID, name, class, subjects, and attendance.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">It has two buttons &#8211; one to add new student information and one to update existing student information. <\/span><span data-preserver-spaces=\"true\">If you click on a student&#8217;s name in the list (table), their information will appear in the text fields at the top, so you can see or change it.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Now the program talks to a database (which is like a big, organized digital cupboard where all this student information is stored). When you add or update information, it saves it to the database. <\/span><span data-preserver-spaces=\"true\">It also fetches and shows information from the database in a table in the window. So you can see all students&#8217; details at once.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">So, it&#8217;s a handy tool for managing student information! <span style=\"font-weight: 400;\">To make the project more interesting, we will implement a simple GUI and use an SQL database to store information regarding student names, classes, subjects &amp; attendance.<\/span><\/span><\/p>\n<h2><a id=\"post-12953-_l5lh0fiypu0s\"><\/a>Objectives<\/h2>\n<p>We have developed this Student Management System in Java to achieve the following objectives:<\/p>\n<p><span data-preserver-spaces=\"true\">1. Create and display a Graphical User Interface (GUI) window where users can interact with the student data.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">2. Allow the user to input student information like ID, Name, Class, Subjects, and Attendance using the GUI.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">3. Provide a way to add new student records to a database by filling in the relevant details and clicking the &#8216;Add Record&#8217; button.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">4. Offer a method to update existing student records in the database using the &#8216;Update Record&#8217; button.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">5. Enable the selection of a student record from the data table, which then populates the input fields with the selected student&#8217;s data for viewing or editing.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">6. Connect to and interact with a MySQL database, allowing the program to retrieve, add, and update student records in the database.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">7. Refresh the data table in the GUI window automatically whenever a new record is added or an existing record is updated, ensuring that the displayed data is always up-to-date.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">8. Handle errors and exceptions, providing useful feedback to the user through dialog messages.<\/span><\/p>\n<h2><a id=\"post-12953-_uo62rjuzzm1k\"><\/a>Requirements<\/h2>\n<p><em>To successfully build and run this student management system in Java, the following technical prerequisites are required:<\/em><\/p>\n<p><strong>1. Java Development Kit (JDK):<\/strong> You need to have the Java Development Kit installed on your system. The version should be compatible with the version used in the code.<\/p>\n<p><strong>2. Java Integrated Development Environment (IDE):<\/strong> A Java IDE such as <a href=\"https:\/\/www.jetbrains.com\/idea\/\">IntelliJ IDEA,<\/a> <a href=\"https:\/\/www.eclipse.org\/downloads\/packages\/release\/kepler\/sr1\/eclipse-ide-java-developers\">Eclipse<\/a>, or <a href=\"https:\/\/netbeans.apache.org\/\">NetBeans<\/a> is required to write and compile the code.<\/p>\n<p><strong>3. Swing Library:<\/strong> The <a href=\"https:\/\/docs.oracle.com\/javase%2F7%2Fdocs%2Fapi%2F%2F\/javax\/swing\/package-summary.html\">Swing library<\/a> is used for creating the Graphical User Interface (GUI) in this code. Swing is included in the standard Java Development Kit (JDK), so you won&#8217;t need to install anything extra if you have JDK.<\/p>\n<p><strong>4. MySQL Database:<\/strong> The code interacts with a MySQL database to store and retrieve student data, so you need to have a MySQL server running. The database should have the correct schema that the code is designed to interact with.<\/p>\n<p><strong>5. MySQL JDBC Driver:<\/strong> This is needed to facilitate the connection between the Java application and the MySQL database. The code use <em><strong>&#8220;com.mysql.cj.jdbc.Driver&#8221;<\/strong><\/em>\u00a0which is a part of MySQL Connector\/J. You&#8217;ll need to include this in your project&#8217;s classpath.<\/p>\n<p><strong>6. Understanding of SQL:<\/strong> You need to understand SQL queries as the code uses SQL for interacting with the database.<\/p>\n<p><strong>7. Knowledge of Java:<\/strong> A good understanding of Java programming language, including its object-oriented programming concepts, exception handling, event handling, and Swing library, is required to comprehend, modify, or build upon this code.<\/p>\n<p><em>[Please note that the exact versions of the JDK, MySQL server, and MySQL JDBC Driver required may depend on the specific details of your project or environment]<\/em><\/p>\n<h2><a id=\"post-12953-_577ca4gmeoq9\"><\/a>Source Code<\/h2>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"java\">package com.company;\r\n\r\npublic

The <\/span><i><span style=\"font-weight: 400;\">\u2018<strong>ADDRECORDButton\u2019 <\/strong><\/span><\/i><span style=\"font-weight: 400;\">allows the user to enter a new student record into the database.

The <strong>\u2018<\/strong><\/span><strong><i>UPDATERECORDButton<\/i><\/strong><span style=\"font-weight: 400;\"><strong>\u2019<\/strong> allows the user to change an existing student record in the database.

The \u2018<\/span><strong><i>tableData<\/i><\/strong><span style=\"font-weight: 400;\"><strong>\u2019<\/strong> method pulls all student records from the database and uses a DefaultTableModel to populate the table with data.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">5. The <em><strong>\u2018<\/strong><\/em><\/span><em><strong>buildTableModel<\/strong><\/em><span style=\"font-weight: 400;\"><em><strong>\u2019<\/strong><\/em> method turns a ResultSet object into a <em><strong>\u2018<\/strong><\/em><\/span><em><strong>DefaultTableModel\u2019<\/strong><\/em><span style=\"font-weight: 400;\">, which is then used to create the table with the retrieved data.<\/span><\/p>\n<p><strong>Moving to retrieving\u00a0information from the SQL database &amp; updating it according to the user\u2019s input, we will apply the following:<\/strong><\/p>\n<p><span data-preserver-spaces=\"true\">1.
