How to develop a form using Java GUI

The following is a basic example of developing code for a form using a Java GUI: import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; public class FormExample { public static void main(String[] args) { //Create a JFrame object as a window container JFrame frame=new JFrame ("form"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Create a JPanel object as the main panel JPanel panel = new JPanel(); //Create various components of the form JLabel nameLabel=new JLabel ("Name:"); JTextField nameField = new JTextField(20); JLabel ageLabel=new JLabel ("Age:"); JTextField ageField = new JTextField(3); JButton submitButton=new JButton ("submit"); //Add components to the panel panel.add(nameLabel); panel.add(nameField); panel.add(ageLabel); panel.add(ageField); panel.add(submitButton); //Add panel to window frame.getContentPane().add(panel); //Set window size and display frame.setSize(300, 200); frame.setVisible(true); } } This is a simple form example, including name, age, and submit button. You can add more components and functions as needed. Running this code will display a window containing the form, where users can enter their name and age, and click the submit button to proceed.
