How Can I Implement Socket Networking in a Java Swing Applet?

Networking with Sockets in a Java Swing Applet

Socket communication allows data exchange between devices over a network. In this context, let's delve into implementing a server-client model using Java Swing and GUI. The goal is to create a socket connection between the server and client, allowing them to pass strings and perform specific actions based on the received string.

To establish the socket connection, we'll create a server using ServerSocket and a client using Socket. The client sends strings to the server, and the server responds by printing the received strings.

Sample Code

The following code provides a simple example of using sockets in a Java Swing applet:

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
import javax.swing.text.DefaultCaret;

public class SwingSocketApplet implements ActionListener {
    private JFrame frame;
    private JTextField textField;
    private JTextArea textArea;
    private JButton sendButton;
    private Socket clientSocket;
    private PrintWriter out;

    public static void main(String[] args) {
        SwingSocketApplet applet = new SwingSocketApplet();
        applet.start();
    }

    public void start() {
        // Create a JFrame for GUI
        frame = new JFrame();
