validate() method is used to cause a container in frames to lay out its subcomponents once again. It should be invoked when this container's subcomponents are modified.

if you change any sub component in a top label container then ,suppose you change some button layout in a frame then that will automatically call by paint to update to validate. that means three method will call one after another . The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame's size explicitly by calling setSize or setBounds (which also sets the frame's location). In general, using pack is preferable to calling setSize, since pack leaves the frame's layout manager in charge of the frame's size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.
