Question

What am I missing here?

 public class abc extends JFrame    {
 private JButton save = new JButton("Save");

 public abc() {
    JPanel p = new JPanel();
    save.addActionListener(new SaveL());
    p.add(save);
    Container cp = getContentPane();
    p = new JPanel();
    p.setLayout(new GridLayout(2, 1));

    cp.add(p, BorderLayout.NORTH);
  }


 }

 class SaveL implements ActionListener {

        public void actionPerformed(ActionEvent e) {    
            System.out.println("Hello"); // nothing happens

        }
}

Why doesn’t my ActionListener work here

Answer 1

You are creating a JPanel, adding your JButton to it, then creating a new JPanel and adding that panel to your JFrame. You need to be adding the original panel to your content pane.
