Content Panes in Java

问题

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 ,

Can some one please clear me the concept of ContentPane and containment hierarchy of Gui Component
