Why is my jButton not functioning? jButton1 is supposed to connect and disconnect from the server.Below is my current code.

package com.chegg; import java.io.*; import java.net.*; public class Client extends javax.swing.JFrame { public Client() { initComponents(); } private void initComponents() {

jLabel1 = new javax.swing.JLabel(); serverName = new javax.swing.JTextField(); jLabel2 = new javax.swing.JLabel(); port = new javax.swing.JTextField(); jButton1 = new javax.swing.JButton(); jScrollPane1 = new javax.swing.JScrollPane(); output = new javax.swing.JTextArea(); jLabel3 = new javax.swing.JLabel(); jLabel4 = new javax.swing.JLabel(); input = new javax.swing.JTextField(); jButton2 = new javax.swing.JButton();

setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

jLabel1.setText("Server:");

serverName.setText("chegg.cloud");

jLabel2.setText("port# :");

port.setText("1234");

jButton1.setText("connect"); jButton1.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { jButton1ActionPerformed(evt); } });

output.setColumns(20); output.setRows(5); jScrollPane1.setViewportView(output);

jLabel3.setText("Client/Server Communication");

jLabel4.setText("Message to Server");

jButton2.setText("send"); jButton2.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { jButton2ActionPerformed(evt); } });
