public interface LayoutManager
Defines the interface for classes that know how to lay outContainers.
Swing's painting architecture assumes the children of aJComponent do not overlap. If aJComponent's LayoutManager allows children to overlap, the JComponent must overrideisOptimizedDrawingEnabled to return false.

Container, JComponent.isOptimizedDrawingEnabled()
