Java : JFrame Issue with Print Statement

I'm facing a problem when the program runs console print the message of frame width and height with getSize() method but when i increase the width of frame with mouse resize.Then i want to update that print statement with that increase width.I don't know how can i do that.
Code

public class Frame extends JFrame {

    public Frame() {

        super("Frame");

        setSize(300, 200);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setVisible(true);

    }

}

Main Method

public class Main {

    public static void main(String[] args) {

        Frame frame = new Frame();

        System.out.println(frame.getSize());

    }

}

Add a ComponentListener to your frame and let the program print the size inside the componentResized method.

frame.addComponentListener(new ComponentListener() {

    @Override
    public void componentHidden(ComponentEvent arg0) {
    }

    @Override
    public void componentMoved(ComponentEvent arg0) {
    }

    @Override
    public void componentResized(ComponentEvent arg0) {
        System.out.println(frame.getSize());
    }

    @Override
    public void componentShown(ComponentEvent e) {

    }
});

Or since we are overriding only one method we can use adapters

frame.addComponentListener(new ComponentAdapter() {
    @Override
    public void componentResized(ComponentEvent arg0) {
        System.out.println(frame.getSize());
    }
});
