PixelGrabber - assistance with code needed

Question

Hello,
I have been trying to get the color of a pixel on an image on a program for the past week. I have been advised to use pixelgrabber, and to save results in an array.
I am trying to understand it by creating a new application just for the purpose of pixelgrabbing, and then coding it properly.
Following the SUN Documentation, i have this code (no errors):
package untitled2;
import java.awt.BorderLayout;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JPanel;
import java.awt.Image;
import java.awt.image.PixelGrabber;
import java.awt.image.ImageObserver;
import java.util.ArrayList;
public class Frame1 extends JFrame {
    JPanel contentPane;
    BorderLayout borderLayout1 = new BorderLayout();
    public void handlesinglepixel(int x, int y, int pixel) {
            int alpha = (pixel >> 24) & 0xff;
            int red   = (pixel >> 16) & 0xff;
            int green = (pixel >>  8) & 0xff;
            int blue  = (pixel      ) & 0xff;
          // Deal with the pixel as necessary...
       public Frame1() {
        try {
            setDefaultCloseOperation(EXIT_ON_CLOSE);
            jbInit();
        } catch (Exception exception) {
            exception.printStackTrace();
    private void jbInit() throws Exception {
        contentPane = (JPanel) getContentPane();
        contentPane.setLayout(borderLayout1);
        setSize(new Dimension(400, 300));
        setTitle("Frame Title");
}Help needed:-
1-Can some show me where to put the code to produce the appropriate image? (do i use normal/buffered/etc)
2-Do i make an array and transfer the values of red,green,blue to postion [0][1][2]?
3-I believe i need to convert the values to an int. How is this done?
4-The "proper" program where this will be used will create multiple images based on user input. The images will be created via a loop.
Are there any issues i should be aware of ? As i understand, each pixelgrabber is unique to each image.. If i have 1000 images will that mean 1000 pixelgrabbers? (slow performance).
Where appropriate, if you could direct me to the relavent tutorial i am happy to read and learn, although i would need help as to the exact location to put the code. For question (1), as i am unsure of the exact image, i would prefer a piece of code (the image is accessed via "temp2.png").

Answer 1

UPDATE
This code shows the rgb value of the image at a specific point (entered in code). all that is needed is to find coordinates within image.
Can anyone help clean code or offer advice?
