JLayeredPane in Java Swing Example

A layered pane is a Swing container which is used to hold the various components using the concept of layers. The components present in the upper layer overlaps the components present in the lower layer. The layered pane is created using the JLayeredPane class. the only constructor of this class is JLayeredPane ().
