Send_data is not abstract and does not override abstract method actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener
how to fix this error??

 
  import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
import java.util.*;
import java.applet.Applet.*;
import java.io.*;
import java.net.*;
 
public class Send_data extends javax.swing.JApplet implements ActionListener  {
    
    private JPanel jContentPane=null;
    private JButton postdata=null;
    public  JTextField jtf=null;
    public String student_name=null,fathers_name=null,dob=null,cont_no=null,cont_email=null,cont_address=null;
    
    /** Creates a new instance of Send_data */
    public Send_data() {
    }
 
    public void init() {
        super.init();
        this.setSize(700,100);
        this.setContentPane(getJContentPane());
    }
    
   public JPanel getJContentPane(){
       
        jContentPane=new JPanel();
        jContentPane.setSize(700,100);
         jContentPane.setLayout(null);
        postdata=new JButton();
        postdata.setFont(new Font("Verdana", 1, 11));
        postdata.setText("Next");
        postdata.setBounds(new Rectangle(625,70,70,20));
        
        jtf=new JTextField();
        jtf.setBounds(new Rectangle(100,70,70,20));
        jContentPane.add(jtf);
        
        jContentPane.add(postdata);
        postdata.addMouseListener(new javax.swing.event.MouseInputAdapter() {
            public void mouseClicked(MouseEvent e) {
                super.mouseClicked(e);  
               
            public void mouseMoved(MouseEvent e) {
                super.mouseMoved(e);
            }
            
        });
      return jContentPane;  
   }
  
}
 

actually i m having a need to use the text entered in JTextField when user click the next button.
can i achieve this using without actionPerformed method??
if i must have to use the actionPerformed method then please help me with code snippet.

thanks in advance

Because you added "implements ActionListener", you are required to implement the actionPerformed method.

Now you could implement that method, or just remove the "implements ActionListener" piece. You're not using the class as an action listener, so implementing it would be useless.
