Create a basic Java Swing UI for an attendance system.

Here's the Java code for a simple user interface layout for the attendance system: `java import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; public class AttendanceSystemUI extends JFrame private JTextField studentNameField; private JTextField studentIdField; private JRadioButton presentRadioButton; private JRadioButton absentRadioButton; private JRadioButton lateRadioButton; private ButtonGroup attendanceGroup; private JButton submitButton; public AttendanceSystemUI() // Step 1: Set up the main frame setTitle("EduTech Academy Attendance System"); setSize(400, 250); // Increased height for better spacing setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setLocationRelativeTo(null); // Center the window // Step 2: Create panels for organization JPanel mainPanel = new JPanel(new BorderLayout(10, 10)); // Main panel with some padding JPanel inputPanel = new JPanel(new GridLayout(3, 2, 5, 5)); // Grid for labels and text fields JPanel attendancePanel = new JPanel(new FlowLayout(FlowLayout.LEFT, 5, 5)); // Flow for radio buttons JPanel buttonPanel = new JPanel(new FlowLayout(FlowLayout.CENTER)); // Flow for submit button // Step 3: Initialize UI components // Student Name inputPanel.add(new JLabel("Student Name:")); studentNameField = new JTextField(20); inputPanel.add(studentNameField); // Student ID inputPanel.add(new JLabel("Student ID:")); studentIdField = new JTextField(20); inputPanel.add(studentIdField); // Attendance Selection attendancePanel.add(new JLabel("Attendance Status:")); presentRadioButton = new JRadioButton("Present"); absentRadioButton = new JRadioButton("Absent"); lateRadioButton = new JRadioButton("Late"); attendanceGroup = new ButtonGroup(); attendanceGroup.add(presentRadioButton); attendanceGroup.add(absentRadioButton); attendanceGroup.add(lateRadioButton); // Select 'Present' by default presentRadioButton.setSelected(true); attendancePanel.add(presentRadioButton); attendancePanel.add(absentRadioButton); attendancePanel.add(lateRadioButton); // Submit Button submitButton = new JButton("Submit"); buttonPanel.add(submitButton); // Step 4: Add components to the main panel mainPanel.add(inputPanel, BorderLayout.NORTH); mainPanel.add(attendancePanel, BorderLayout.CENTER); mainPanel.add(buttonPanel, BorderLayout.SOUTH); // Add padding to the main panel mainPanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); // Add the main panel to the frame add(mainPanel); // Step 5: Add action listener for the submit button (for demonstration) submitButton.addActionListener(new ActionListener() @Override public void actionPerformed(ActionEvent e) String studentName = studentNameField.getText(); String studentId = studentIdField.getText(); String attendanceStatus = ""; if (presentRadioButton.isSelected()) attendanceStatus = "Present"; else if (absentRadioButton.isSelected()) attendanceStatus = "Absent"; else if (lateRadioButton.isSelected()) attendanceStatus = "Late"; // For a real system, this data would be saved to a database or file. // Here, we just display it in a dialog. JOptionPane.showMessageDialog(AttendanceSystemUI.this, "Student Name: " + studentName + "" + "Student ID: " + studentId + "" + "Attendance Status: " + attendanceStatus, "Attendance Recorded", JOptionPane.INFORMATION_MESSAGE); // Clear fields after submission studentNameField.setText(""); studentIdField.setText(""); presentRadioButton.setSelected(true); // Reset to default ); public static void main(String[] args) // Ensure the UI is created and updated on the Event Dispatch Thread SwingUtilities.invokeLater(new Runnable() @Override public void run() new AttendanceSystemUI().setVisible(true); ); ` Explanation: 1. JFrame: This is the main window of the application. We set its title, size, default close operation, and center it on the screen. 2. JPanel: Used for organizing components. mainPanel: Uses BorderLayout to arrange the input fields at the top (NORTH), attendance selection in the middle (CENTER), and the submit button at the bottom (SOUTH). inputPanel: Uses GridLayout to arrange the "Student Name" and "Student ID" labels with their respective text fields in a 3x2 grid. attendancePanel: Uses FlowLayout to arrange the "Attendance Status" label and the radio buttons horizontally. buttonPanel: Uses FlowLayout to center the "Submit" button. 3. JLabel: Used to display static text labels like "Student Name:", "Student ID:", and "Attendance Status:". 4. JTextField: These are editable text boxes where the teacher can enter the student's name and ID. 5. JRadioButton and ButtonGroup: JRadioButtons allow the selection of one option from a set. The ButtonGroup ensures that only one of "Present," "Absent," or "Late" can be selected at a time. "Present" is set as the default selection. 6. JButton: This is the "Submit" button. An ActionListener is added to it to demonstrate what happens when it's clicked (in a real application, this would save data to a database; here, it shows a confirmation dialog). 7. SwingUtilities.invokeLater: This ensures that the GUI creation and updates are performed on the Event Dispatch Thread (EDT), which is crucial for thread-safe Swing applications. This code provides a functional and clear user interface layout as requested. 3 done, 2 left today. You're making progress.
