title: How to set absolute position on JPanel which in BorderLayout
body: <p>I have a main panel that looks like this:</p>
  
  <pre><code>JPnael mainPanel = new JPanel();
  mainPanel .setLayout(new BorderLayout());
  </code></pre>
  
  <p>And I include sub panels, like this:</p>
  
  <pre><code>mainPanel.add(new JPanel(), BorderLayout.NORTH));
  mainPanel.add(new JPanel(), BorderLayout.CENTER));
  </code></pre>
  
  <p>I want to create another JPanel, but not in BorderLayout, it needs to be absolute position. How can I do this?</p>
  
  <p>Update:
  I tried this variant, but it not suitable for BorderLayout</p>
  
  <pre><code>JPanel absPanel = new JPanel();
  JLabel absLbl = new JLabel("aaaaaaaaa");
  absPanel.setLayout(null);
  absPanel.add(absLbl);
  absPanel.setBounds(0, 0, 100, 100);
  mainPanel.add(absPanel, ???);
  </code></pre>
