What’s the biggest and smallest number that can be used in: pane.add() ?

public class Main {

    public static void main(String[] args) {

        JLayeredPane pane = new JLayeredPane();
        pane.setPreferredSize(new Dimension(500,500));
        pane.setBackground(Color.pink);
        pane.setOpaque(true);

        JPanel blueBox = new JPanel();
        blueBox.setBounds(100,100,100,100);
        blueBox.setBackground(Color.BLUE);

        JPanel redBox = new JPanel();
        redBox.setBounds(150,100,100,100);
        redBox.setBackground(Color.RED);


        pane.add(blueBox, Integer.valueOf(-948884));
        pane.add(redBox, Integer.valueOf(1009499595));


        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(pane);
        frame.pack();
        frame.setVisible(true);


    }
}

I read the docs but didn’t find the answer: https://docs.oracle.com/en/java/javase/17/docs/api/java.desktop/javax/swing/JLayeredPane.html

My guess is: the smallest number is the smallest int number and the largest is the biggest int number but i want to be sure ????
