Swing is a part of the JFC (Java Foundation Classes). Building Graphical User Interface in Java requires the use of Swings. Swing Framework contains a large set of components which allow a high level of customization and provide rich functionalities, and is used to create window-based applications. Java swing components are lightweight, platform-independent, provide powerful components like tables, scroll panels, buttons, list, colour chooser, etc.

In this article, we will see how to write the students information in a Jframe and store it in a file.

Approach: To solve this problem, the following steps are followed:

  1. First, we need to create a frame using JFrame.
  2. Next create JLabels, JTextFields, JComboBoxes, JButtons and set their bounds respectively.
  3. Name these components accordingly and set their bounds.
  4. Now, in order to save the data into the text file on button click, we need to add Event Handlers. In this case, we will add ActionListener to perform an action method known as actionPerformed in which first we need to get the values from the text fields which is default as a “string”.
  5. Finally, the Jbuttons, JLabels, JTextFields and JComboBoxes are added to the JFrame and the text is stored in a text file.

Below is the implementation of the above approach:

// Java program to write a student
// information in JFrame and
// storing it in a file
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class GFG {
    // Function to write a student
    // information in JFrame and
    // storing it in a file
    public static void StudentInfo()
        // Creating a new frame using JFrame
        JFrame f
            = new JFrame(
                "Student Details Form");
        // Creating the labels
        JLabel l1, l2, l3, l4, l5;
        // Creating three text fields.
        // One for student name, one for
        // college mail ID  and one
        // for  Mobile No
        JTextField t1, t2, t3;
        // Creating two JComboboxes
        // one for Branch and one
        // for Section
        JComboBox j1, j2;
        // Creating  two buttons
        JButton b1, b2;
        // Naming the labels and setting
        // the bounds for the labels
        l1 = new JLabel("Student Name:");
        l1.setBounds(50, 50, 100, 30);
        l2 = new JLabel("College Email ID:");
        l2.setBounds(50, 120, 120, 30);
        l3 = new JLabel("Branch:");
        l3.setBounds(50, 190, 50, 30);
        l4 = new JLabel("Section:");
        l4.setBounds(420, 50, 70, 30);
        l5 = new JLabel("Mobile No:");
        l5.setBounds(420, 120, 70, 30);
        // Creating the textfields and
        // setting the bounds for textfields
        t1 = new JTextField();
        t1.setBounds(150, 50, 130, 30);
        t2 = new JTextField();
        t2.setBounds(160, 120, 130, 30);
        t3 = new JTextField();
        t3.setBounds(490, 120, 130, 30);
        // Creating two string arrays one for
        // braches and other for sections
        String s1[]
            = { "  ", "CSE", "ECE", "EEE",
                "CIVIL", "MEC", "Others" };
        String s2[]
            = { "  ", "Section-A", "Section-B",
                "Section-C", "Section-D",
                "Section-E" };
        // Creating two JComboBoxes one for
        // selecting branch and other for
        // selecting the section
        // and setting the bounds
        j1 = new JComboBox(s1);
        j1.setBounds(120, 190, 100, 30);
        j2 = new JComboBox(s2);
        j2.setBounds(470, 50, 140, 30);
        // Creating one button for Saving
        // and other button to close
        // and setting the bounds
        b1 = new JButton("Save");
        b1.setBounds(150, 300, 70, 30);
        b2 = new JButton("close");
        b2.setBounds(420, 300, 70, 30);
        // Adding action listener
        b1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e)
                // Getting the text from text fields
                // and JComboboxes
                // and copying it to a strings
                String s1 = t1.getText();
                String s2 = t2.getText();
                String s3 = j1.getSelectedItem() + "";
                String s4 = j2.getSelectedItem() + "";
                String s5 = t3.getText();
                if (e.getSource() == b1) {
                    try {
                        // Creating a file and
                        // writing the data
                        // into a Textfile.
                        FileWriter w
                            = new FileWriter(
                                "GFG.txt", true);
                        w.write(s1 + "\n");
                        w.write(s2 + "\n");
                        w.write(s3 + "\n");
                        w.write(s4 + "\n");
                        w.write(s5 + "\n");
                    catch (Exception ae) {
                // Shows a Pop up Message when
                // save button is clicked
                        "Successfully Saved"
                            + " The Details");
        // Action listener to close the form
        b2.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e)
        // Default method for closing the frame
        f.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e)
        // Adding the created objects
        // to the frame
        f.setSize(700, 600);
    // Driver code
    public static void main(String args[])
