title: Content Panes in Java
body: <p>I am  new to programming and was  just studying  JFrame etc ,  here i read   ContentPane  Like this  "Components go in the "content pane", not directly in the frame."  when  i did search COntentpane  i  read containment hierarch  that is pretty confusing for me to understand ,  </p>
  
  <p>Can some one  please  clear me the concept of ContentPane and  containment hierarchy of Gui Component </p>
