Blank JFrame when program is run

Question

I am an absolute beginner in coding. I would like to know why is my Jframe blank when run, how do I fix it. From what I have research on the internet it seems that I should put the component inside the JFrame as it is empty but how do I do it

My Code

public class Video extends JFrame
{

public static void main(String[] args) throws URISyntaxException {

final URI uri = new URI("https://www.youtube.com/watch?v=rl0YiZjTqpw");

class OpenUrlAction implements ActionListener 
{
  @Override public void actionPerformed(ActionEvent e) {
    open(uri);
  }
}

JFrame frame = new JFrame("Links");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(410, 400);
Container container = frame.getContentPane();
container.setLayout(new GridBagLayout());
JButton btnclickHereTo = new JButton();
btnclickHereTo.setText("<HTML> <FONT color=\"#000099\"><U>Click Here To Watch Video</U></FONT>");
btnclickHereTo.setHorizontalAlignment(SwingConstants.LEFT);
btnclickHereTo.setBorderPainted(false);
btnclickHereTo.setOpaque(false);
btnclickHereTo.setBackground(Color.WHITE);
btnclickHereTo.setToolTipText(uri.toString());
btnclickHereTo.addActionListener(new OpenUrlAction());
container.add(btnclickHereTo);
frame.setVisible(true);
}
private static void open(URI uri) 
{
    if (Desktop.isDesktopSupported()) 
    {
      try 
      {
        Desktop.getDesktop().browse(uri);
      }
      catch (IOException e) 
      { /* TODO: error handling */ }
    }
    else
    { /* TODO: error handling */ }
  }

}

btw: your code should be a copy-pastable text and not a screenshot — ΦXocę 웃 Пepeúpa ツ, Aug 01 '17 at 15:08
You could take a look at https://stackoverflow.com/questions/7201722, which seems to be related to your question. — Freek de Bruijn, Aug 01 '17 at 21:33

public void setVisible(boolean b) {

Why would you override the setVisible(...) method of your frame? There is no reason to do that.

Start with something basic, like the example from the Swing tutorial on How to Make Frames.

Keep a reference to the tutorial link handy since it contains information and examples for all Swing basics.

@DarenLua, read the tutorial for a working example. There is also example code for using the "Desktop" API. You need to spend time reading to learn Swing. – camickr Aug 01 '17 at 17:00
