Adding a JButton when another JButton is pressed

I have a JButton which I want to create a new JButton with when it is pressed I have added an ActionListener that looks like this, but it doesn't add another JButton.

public void actionPerformed(ActionEvent e){
        Object command = e.getSource();
        if(command.equals(play)){
            ImageIcon i1 = new ImageIcon("NewGame.png");
            width = i1.getIconWidth();
            height = i1.getIconWidth();
            newGame = new JButton(i1);
            newGame.setBorderPainted(false);
            newGame.setContentAreaFilled(false);
            newGame.setSize(width, height);
            newGame.setLocation(600,100);
            add(newGame);
            System.out.println("It Works");
        } 
    }

How would I make it so that when I press the already existing JButton this one will be added?

if you are not getting exception, then you will need to refresh or repaint the container which will old the new button.

Make sure to revalidate and repaint after adding the button

revalidate();
repaint();

From the use of setSize and setLocation, it appears you are using a absolute positioning or null layout. Use a layout manager.

You must call repaint() after adding it.
