swing - Java setBounds not working with JPanel

Question

i am doing a small Gui in java. i am using setBounds methods to set the position of buttons etc on my JFrame , but problem is that when i use it with JPanel button is not visible on JFrame , and without JPanel its quite ok ,, see both the codes and please help me as i am beginner and facing these foolish problems .

This one is working fine

  JFrame jframe = new JFrame("Working Fine");  
  jframe.setLayout(null);  
  JButton jbutton = new JButton("Position Test");  
  jbutton.setBounds(0, 0, 100, 100);  
  jframe.add(jbutton);  
  jframe.setSize(300,300);
  jframe.setVisible(true);

Same code when i add Button to Jpanel then it does not work so whats wrong , please guide me

  JFrame jframe = new JFrame("causing problem ");
  jframe.setSize(300,300);
  JPanel p = new JPanel();
  jframe.setLayout(null);  
  JButton jbutton = new JButton("Position Test");  
  jbutton.setBounds(0, 0, 100, 100);
  jframe.add(p);
  p.add(jbutton);
  p.setVisible(true);
 //jframe.add(jbutton);  
  jframe.setVisible(true);

please help me in this small problem

You must get rid of the JPanel's layout, in order to set absolute positions:

p.setLayout(null);
