How to close child jFrames automatically when i close the parent?

Question

I have a parent JFrame and two 'child' JFrames in package JFrame. Imagine I open parent JFrame and then it's child JFrames - currently all 3 forms are open. Now I close parent JFrame.

What should I do to close all child frames automatically after close their parent JFrame?
Here is my code:

class Parent:
public class Parent extends JFrame {

public Parent() {

    JButton child1 = new JButton("child1");
    child1.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            new Child1().setVisible(true);;
        }
    });

    JButton child2 = new JButton("child2");
    child2.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            new Child2().setVisible(true);
        }
    });
    JButton closeAllJframe = new JButton("closeAllJframe");
    closeAllJframe.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            dispose();
        }
    });

    this.setBounds(500, 200, 400, 200);
    this.addWindowListener(new WindowAdapter() {
        @Override
        public void windowClosing(WindowEvent e) {
            dispose();
        }
    });
    JPanel jPanel = new JPanel();
    jPanel.add(child1);
    jPanel.add(child2);
    jPanel.add(closeAllJframe);
    this.add(jPanel);
}

@Override
public void dispose() {
    super.dispose();
}

public static void main(String[] args) {
    new Parent().setVisible(true);
}}

class Child1:

public class Child1 extends JFrame {

public Child1() {
    this.setBounds(200, 300, 300, 200);
    this.setTitle("child 1");
}}

class Child2:

public class Child2 extends JFrame {

public Child2() {
    this.setBounds(200, 300, 300, 200);
    this.setTitle("child 1");
}}

if it's jframes, then add window listener and call dispose on child jframes on window closing event. — Coderino Javarino, Jul 04 '16 at 13:49
1) Tip: Add @FastSnail (or whoever, the `@` is important) to *notify* the person of a new comment. 2) For better help sooner, post a [MCVE] or [Short, Self Contained, Correct Example](http://www.sscce.org/). 3) See [The Use of Multiple JFrames, Good/Bad Practice?](http://stackoverflow.com/q/9554636/418556) Tip: The 'child frames' whould be dialogs instead. — Andrew Thompson, Jul 04 '16 at 13:58

child frames? There is no childhood in between frame in Swing. Be more precise... Describe exactly what's inside you UI. — Jean-Baptiste Yunès, Jul 04 '16 at 16:44
@Jean-BaptisteYunès *"Describe exactly what's inside you UI."* An MCVE/SSCCE is superb for doing just that. — Andrew Thompson, Jul 05 '16 at 00:03

Add an window listener to the frame then implements the windowClosed(WindowEvent e) method Javadoc about WindowListener
