Closing a JFrame using a button in eclipse

Question

I'm a rookie when it comes to programming. We have this project about a log-in profile account. I just started doing it; and I came across a specific problem. I want to close a frame using a button.

buttonenter.setText("Enter");
     buttonenter.addActionListener(new ActionListener (){
       public void actionPerformed (ActionEvent ae){

           }
    });

I tried placing my frame.dispose();, set.Visible(false) etc. but i just got an error. I don't quite get. I really appreciate the help! Thank you!

Here's a simple example of what you're trying to do. What errors are you receiving?

private void initialize() {
    frame = new JFrame();
    frame.setBounds(100, 100, 450, 300);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JButton btnClose = new JButton("CLOSE");
    btnClose.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            frame.setVisible(false);
        }
    });
    frame.getContentPane().add(btnClose, BorderLayout.NORTH);
}
