With reference to sun's tutorial

Sun's Tutorial

To appear onscreen, every GUI component must be part of a containment hierarchy. A containment hierarchy is a tree of components that has a top-level container as its root. We'll show you one in a bit.



What does containment hierarchy here mean? Does it mean the class-hierarchy or hierarchy of the components being laid out logically? If it is the latter one, where may i find its details?

As it says in your quoted text above, "A containment hierarchy is a tree of components that has a top-level container as its root. " It's your second option. Now, perhaps you misused the word "latter" -- it seems like the second one shouldn't need any more information. In general, a containment hierarchy has a JFrame or JDialog (or Frame or Dialog or plain Window) at the top, with some JPanels or Panels or Canvases inside, with some JButtons or JLabels or Choices or any other components inside those -- but you knew that already.
