ActionListener taskPerformer = new ActionListener() 


     public ExitScreen() {
         initComponents();
        
         Timer t = new Timer(1000, taskPerformer);
         t.start();
     }

      public void actionPerformed(ActionEvent e) {

         this.dispose();

         System.exit(0);
       
    }

when i do it that way, i get an error at ActionListener taskPerformer = new ActionListener()

i get the error

java.awt.event.ActionListener is abstract; cannot be instantiated

here is my complete code, if it helps

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Timer;

public class ExitScreen extends javax.swing.JFrame {
  


    ActionListener taskPerformer = new ActionListener();

        
    

     public ExitScreen() {
         initComponents();
        
         Timer t = new Timer(1000, taskPerformer);
         t.start();
     }

      public void actionPerformed(ActionEvent e) {

         this.dispose();

this is what i got and it doesn't work

ActionListener taskPerformer = new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
    };
    

     public ExitScreen() {
         initComponents();
        
         Timer t = new Timer(1000, taskPerformer);
         t.start();
     }

      public void actionPerformed(ActionEvent e) {

         this.dispose();

         System.exit(0);
       
    }

It worked perfectly!! thanks!

thanks for the help. It was actually a stupid mistake from my side.
'team' was supposed to be 'teams'
thanks again!

alright this is my working code

String newTourney = JOptionPane.showInputDialog("Enter tournament name");
try{
  
            ResultSet rs = soccer.queryTbl("CREATE TABLE "+newTourney+"(Team char(20))");
            
            
rs.close();
        }
      catch(SQLException e)
    {
        System.out.println(e.getMessage());
    }

how can i edit that code to output a message using JOptionPane.showMessageDialog if the new tournament entered already exists
