Getting a JPanel to appear above another one

[Andross561]

I have a frame, that has two components. A JComponent and a JLabel. The JLabel takes up the entire frame, but I want the JComponent to appear above it. Right now it is hiding beneath the JLabel. Any help would be appreciated! here is the code \

import java.applet.Applet;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JPanel;

import javax.swing.JLabel;


public class Main extends JPanel{
	private static int frameWidth;
	private static int frameHeight;
	private static BufferedImage img = null;
	/**
	 * @param args
	 */
	
	private static BufferedImage createImage(){
		try {
		    img = ImageIO.read(new File("Ithaca College Campus Map.PNG"));
		  //  System.out.println(img);
		    return img;
		} 
		catch (IOException e) {
		}
		return null;
	}
	public void paint(Graphics g) {
		g.drawImage(img, 0, 0, frameWidth, frameHeight, null);
	}
	public static void main(String[] args) {
		JFrame frame = new JFrame();
		MyComponent component = new MyComponent();
		createImage();
		frameWidth = img.getWidth();
		frameHeight = img.getHeight();
		JLabel picLabel = new JLabel(new ImageIcon( img ));
		
		frame.getContentPane().add(component);
		//picLabel.add(new MyComponent());
		frame.getContentPane().add(picLabel);
		
		//picLabel.add(new MyComponent());
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(frameWidth, frameHeight);
		frame.setVisible(true);
		frame.repaint();
	}
	
}
	class MyComponent extends JComponent {
		// slices is an array of values that represent the size of each slice.
		public void drawPie(Graphics2D g, Rectangle area, PieValue[] slices) {
		    // Get total value of all slices
		    double total = 0.0D;
		    for (int i=0; i<slices.length; i++) {
		        total += slices[i].value;
		    }

		    // Draw each pie slice
		    double curValue = 0.0D;
		    int startAngle = 0;
		    for (int i=0; i<slices.length; i++) {
		        // Compute the start and stop angles
		        startAngle = (int)(curValue * 360 / total);
		        int arcAngle = (int)(slices[i].value * 360 / total);

		        // Ensure that rounding errors do not leave a gap between the first and last slice
		        if (i == slices.length-1) {
		            arcAngle = 360 - startAngle;
		        }

		        // Set the color and draw a filled arc
		        g.setColor(slices[i].color);
		        g.fillArc(area.x, area.y, area.width, area.height, startAngle, arcAngle);

		        curValue += slices[i].value;
		    }
		}
	    PieValue[] slices = new PieValue[4];

	    MyComponent() {
	        slices[0] = new PieValue(25, Color.red);
	        slices[1] = new PieValue(33, Color.green);
	        slices[2] = new PieValue(20, Color.pink);
	        slices[3] = new PieValue(15, Color.blue);
	    }

	    // This method is called whenever the contents needs to be painted
	    public void paint(Graphics g) {
	        // Draw the pie
	        drawPie((Graphics2D)g, new Rectangle(0,0, 400, 400), slices);
	    }
	}

Um, doWhile, wrong link?

A JFrame's contentPane has a BorderLayout by default.

Good point...I was thinking in 3 dimensions. I guess it depends what 'above' and 'below' actually mean in the original post.

I have two images, one is a campus map, while the other is a pie chart, I need the pie chart to be on top of the campus map so both images are visible.

You've been given links to two tutorials, at least one of which is sure to be relevant to your still vague requirement. So, are you going to buckle down and learn something from the tutorials, or are you going to hang around here stating and re-stating your requirement in the same ambiguous terms?
