JLayeredPane is a Swing container that provides the ability to add components at different depths or layers, allowing for overlapping of components within a single container. This can be useful for creating complex user interfaces where components need to be stacked on top of each other, such as in graphical editors or games.

The JLayeredPane class extends the JComponent class and provides several methods for manipulating the position and depth of the components that it contains. Here are some examples of how to use JLayeredPane:

1. Creating a JLayeredPane instance:

JLayeredPane layeredPane = new JLayeredPane();

2. Adding components to the JLayeredPane with a specific depth:

JButton button1 = new JButton("Button 1");
layeredPane.add(button1, JLayeredPane.DEFAULT_LAYER);

JButton button2 = new JButton("Button 2");
layeredPane.add(button2, JLayeredPane.PALETTE_LAYER);

3. Changing the depth of a component:

layeredPane.setLayer(button1, JLayeredPane.PALETTE_LAYER);

4. Retrieving the depth of a component:

int depth = layeredPane.getLayer(button1);

5. Changing the position of a component within its layer:

layeredPane.setPosition(button1, 10, 10);

6. Retrieving the position of a component within its layer:

Point position = layeredPane.getPosition(button1);

7. Setting the size of the JLayeredPane:

layeredPane.setPreferredSize(new Dimension(400, 300));

Note that JLayeredPane does not provide any layout functionality, so you will need to position and size the components manually.
