How can i make the java class seperate into an MVC pattern?

public class ChatView implements ActionListener
{
   public static void main(String[] args)
   {
       JFrame chatFrame = new JFrame();
       JFrame chatFrame1 = new JFrame();
       JFrame chatFrame2 = new JFrame();
      
       JPanel chatPanel = new JPanel();
       JPanel chatPanel1 = new JPanel();
       JPanel chatPanel2 = new JPanel();
       chatFrame.setContentPane(chatPanel);
       chatFrame1.setContentPane(chatPanel1);
       chatFrame2.setContentPane(chatPanel2);
       chatFrame.setLayout(new FlowLayout());
       chatFrame1.setLayout(new FlowLayout());
       chatFrame2.setLayout(new FlowLayout());
       JTextField chatWrite = new JTextField();
       JTextField chatWrite1 = new JTextField();
       JTextField chatWrite2 = new JTextField();
       JTextArea chatDisplay = new JTextArea();
       JTextArea chatDisplay1 = new JTextArea();
       JTextArea chatDisplay2 = new JTextArea();
       JButton chatButton = new JButton("Send Message");
       JButton chatButton1 = new JButton("Send Message");
       JButton chatButton2 = new JButton("Send Message");
       chatDisplay.setPreferredSize(new Dimension(500, 450));
       chatDisplay1.setPreferredSize(new Dimension(500, 450));
       chatDisplay2.setPreferredSize(new Dimension(500, 450));
       chatDisplay.setEditable(false);
       chatDisplay1.setEditable(false);
       chatDisplay2.setEditable(false);
       chatWrite.setPreferredSize(new Dimension(300, 30));
       chatWrite1.setPreferredSize(new Dimension(300, 30));
       chatWrite2.setPreferredSize(new Dimension(300, 30));
       chatButton.addActionListener(new ActionListener()
       {
           public void actionPerformed(ActionEvent event)
           {
               String phrase = chatWrite.getText();
               chatDisplay.append("Derek: " + phrase + "\n");
               chatDisplay1.append("Derek: " + phrase + "\n");
               chatDisplay2.append("Derek: " + phrase + "\n");
               chatWrite.setText("");
           }
       });
      
       chatButton1.addActionListener(new ActionListener()
       {
           public void actionPerformed(ActionEvent event)
           {
               String phrase = chatWrite1.getText();
               chatDisplay.append("Ben: " + phrase + "\n");
               chatDisplay1.append("Ben: " + phrase + "\n");
               chatDisplay2.append("Ben: " + phrase + "\n");
               chatWrite1.setText("");
           }
       });
      
       chatButton2.addActionListener(new ActionListener()
       {
           public void actionPerformed(ActionEvent event)
           {
               String phrase = chatWrite2.getText();
               chatDisplay.append("Steve: " + phrase + "\n");
               chatDisplay1.append("Steve: " + phrase + "\n");
               chatDisplay2.append("Steve: " + phrase + "\n");
               chatWrite2.setText("");
           }
       });
      
       chatPanel.add(chatDisplay);
       chatPanel1.add(chatDisplay1);
       chatPanel2.add(chatDisplay2);
       chatPanel.add(chatWrite);
       chatPanel1.add(chatWrite1);
       chatPanel2.add(chatWrite2);
       chatPanel.add(chatButton);
       chatPanel1.add(chatButton1);
       chatPanel2.add(chatButton2);
       chatFrame.setSize(new Dimension(600, 600));
       chatFrame1.setSize(new Dimension(600, 600));
       chatFrame2.setSize(new Dimension(600, 600));
       chatFrame.setLocationRelativeTo(null);
       chatFrame1.setLocationRelativeTo(null);
       chatFrame2.setLocationRelativeTo(null);
       chatFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       chatFrame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       chatFrame2.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       chatFrame.setTitle("Chat Room - Derek");
       chatFrame1.setTitle("Chat Room - Ben");
       chatFrame2.setTitle("Chat Room - Steve");
       chatFrame.setVisible(true);
       chatFrame1.setVisible(true);
       chatFrame2.setVisible(true);

   }

   @Override
   public void actionPerformed(ActionEvent e) {
       // TODO Auto-generated method stub
      
   }

  
}

Explanation:

Hi,

We can not break a single class into the MVC pattern. This has a valid reason. Let me explain...

What is MVC?

MVC Model View Controller.

When we define a project we should keep separating the view logic and DB classes.

So here the model is DB part, View is view(HTML) part and controller have logic and bind all of three.

So in the MVC pattern, we have three different parts.

Hope You understood. If not comment below. I will clear you.

Thanks
