title: .setLocation and .setBounds not working on JLabel! (and JButton)
body: <p>So I have looked through ton of topics about this, but none seem to fix my problem!
  When I try to use setBounds() or setLocation() on JLabel or JButton it just doesn't work! It seems to place both of them just randomly.
  Here is my code:</p>
  
  <pre><code>public static void main(String[] args) {
      final JFrame frame = new JFrame(TITLE);
      final JLabel fpsLabel = new JLabel("FPS: ERROR");
      final JLabel fpsDone = new JLabel("FPS done: ERROR");
      final JPanel contentPanel = new JPanel();
  
      frame.setSize(WIDTH, HEIGHT);
              frame.setContentPane(contentPanel);
      frame.setLocationRelativeTo(null);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      fpsLabel.setLocation(WIDTH / 2, HEIGHT / 6);
      fpsDone.setLocation(200, HEIGHT / 6);
      frame.setJMenuBar(menubar);
      frame.setResizable(false);
      frame.add(fpsLabel);
      frame.add(fpsDone);
      frame.setVisible(true);
  }
  </code></pre>

  <pre><code>public static void main(String[] args) {
              final JFrame frame = new JFrame("Example SSCCE");
              final JLabel fpsLabel = new JLabel("FPS: ERROR");
              final JLabel fpsDone = new JLabel("FPS done: ERROR");
              final JPanel contentPanel = new JPanel();
              final int HEIGHT = 400 / 16 * 9;
  
              frame.setSize(400, HEIGHT);
              frame.setContentPane(contentPanel);
              fpsDone.setLocation(200, HEIGHT / 2);
              fpsLabel.setLocation(200, HEIGHT / 2 + 50);
              contentPanel.add(fpsDone);
              contentPanel.add(fpsLabel);
              frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
              frame.setVisible(true);
      }
