JLayeredPane isnt displaying

[rasen58]

In my applet, I have a layered pane, but it isnt showing. Can you tell me why?

import javax.swing.*;

import java.awt.*;

public class birthday extends JApplet
{
	JPanel panel;
	JLayeredPane pane;
	JLabel background;
	ImageIcon card;
	JButton enter;
	JLabel label;
	JPasswordField pass;
	JProgressBar progress;
	
	
	public void init()
	{
		setLayout(new FlowLayout());
		setSize(700, 600);
		
		pane = new JLayeredPane();
		pane.setPreferredSize(new Dimension(400, 410));
		
		card = new ImageIcon(getClass().getResource("jfdlk.png"));
		background = new JLabel();
		background.setIcon(card);
		//background.setOpaque(true);
		//pane.add(background, 1);
		
		enter = new JButton("Press Me!");
		//pane.add(enter, JLayeredPane.DEFAULT_LAYER);
		pane.add(enter, new Integer(1));
		JButton t2 = new JButton();
		t2.setBackground(Color.white);
		pane.add(t2, new Integer(0));
		//panel = new JPanel();
		//panel.add(pane);
		//panel.add(enter);
		
		add(pane);
		//add(enter);
		//getContentPane().add(panel);
		
		
		
		
	}
	
}

Never mind I figured it out, there was not layout in the pane, so I had to set the bounds myself. thanks anyway. But I do have a question, why must you put new Integer(x) in pane.add()? Why can't you just put x?
