有没有一种方法可以在一个JLayeredPane中插入多个JScrollPanes？

import javax.swing.*;
import java.awt.*;

public class MultipleScrollPanesExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Multiple Scroll Panes Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 400);

        JLayeredPane layeredPane = new JLayeredPane();
        layeredPane.setLayout(new FlowLayout());

        // Create and add multiple JScrollPanes
        JScrollPane scrollPane1 = new JScrollPane(new JLabel("ScrollPane 1"));
        JScrollPane scrollPane2 = new JScrollPane(new JLabel("ScrollPane 2"));
        JScrollPane scrollPane3 = new JScrollPane(new JLabel("ScrollPane 3"));

        layeredPane.add(scrollPane1, new Integer(0));
        layeredPane.add(scrollPane2, new Integer(1));
        layeredPane.add(scrollPane3, new Integer(2));

        frame.add(layeredPane);
        frame.setVisible(true);
    }
}
