在JButton中隐藏JFrame和匿名ActionListener

Question

I have a welcome (or menu) window (JFrame) with some buttons (JButton) for each possible action. Each of these should launch a new window and hide the welcome window. I know I can do it with setVisible(false); . But I can't make it work yet.

This is one example of code I have:

    _startBtn.addActionListener(new ActionListener(){
        @Override
        public void actionPerformed(ActionEvent e){
            System.out.println("_startBtn pressed");
            // Code to hide this JFrame and initialize another
        }

My question is, how can I do it using a anonymous class like this one?

Thanks in advance!

I am posting an example for you i hope it will help you.

import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;


public class windows_test {
    JFrame login = null;
    JFrame inner_frame = null;

    public windows_test() {
        login = new JFrame();
        login.setBounds(10, 10, 300, 300);
        login.setLayout(new BorderLayout());

        JButton button = new JButton("Login");
        login.add(button, BorderLayout.CENTER);

        login.setVisible(true);

        button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent arg0) {
                if (inner_frame == null) {
                    inner_frame = new JFrame();
                }
                inner_frame.setLayout(new FlowLayout(FlowLayout.CENTER));
                inner_frame.add(new JButton("inner frame"));
                inner_frame.setVisible(true);
                login.setVisible(false);
                inner_frame.setBounds(10, 10, 300, 300);
            }
        });
    }
}

I will recommend you to use jpanel instead of jframes but you have asked for frames so i have created it with them. Hope it will help you ask if i am wrong somewhere or you are not able to understand.
