Object access between classes

[qazplm123890]

Hello! I'm new to Java Forums, but I have a question. In the following code, how could I make the scroll() method into it's own class but let is still be able to access/edit the camera object with the least coding jumble possible. Thank you!

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

public class ScrollTest extends JPanel {

	JFrame frame;
	static JPanel screen;
	Camera camera;

	public static void main (String[] args) {
		ScrollTest gui = new ScrollTest();
		gui.go();

	}

	public void go() {

		setUpGUI();
		scroll(camera.getX(), camera.getY(), 1400, 350, 390, 130, 50, 20, 'l');

	}

	public void setUpGUI() {

		frame = new JFrame("Scrolling Test");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		screen = new JPanel();
		camera = new Camera();

		screen.setLayout(null);
		screen.setSize(350,130);
		camera.setLayout(null);
		camera.setSize(1400,390);

		screen.add(camera);

		camera.setLocation(0,0);

		frame.getContentPane().add(BorderLayout.CENTER, screen);
		//(6,38) pixels used on frame.
		frame.setSize(356,168);
		frame.setResizable(false);
		frame.setVisible(true);

	}

	public void scroll(int currentX, int currentY, int width, int visWidth, int height, int visHeight, int dist, int msDelay, char dir) {

		if (dir == 'l') {
			for (int i = currentX; i>-(width - visWidth) && i>=(currentX - dist); i--) {

				camera.setLocation(i,0);
				try {
					Thread.sleep(msDelay);
				} catch(InterruptedException ex) {
					ex.printStackTrace();
				}
			}
		}

		else if (dir == 'r') {
			for (int i = currentX; i<=0 && i<=(currentX + dist); i++) {

				camera.setLocation(i,0);
				try {
					Thread.sleep(msDelay);
				} catch(InterruptedException ex) {
					ex.printStackTrace();
				}
			}
		} 

		else if (dir == 'u') {
			for (int i = currentY; i>=-(height - visHeight) && i>=(currentY - dist); i--) {

				camera.setLocation(0,i);
				try {
					Thread.sleep(msDelay);
				} catch(InterruptedException ex) {
					ex.printStackTrace();
				}
			}
		}

		else if (dir == 'd') {
			for (int i = currentY; i<=0 && i<=(currentY + dist); i++) {

				camera.setLocation(0,i);
				try {
					Thread.sleep(msDelay);
				} catch(InterruptedException ex) {
					ex.printStackTrace();
				}
			}
		}
	}

	class Camera extends JPanel {

		public void paintComponent(Graphics g) {

			Image background = new ImageIcon("images\\TestBackground.png").getImage();

			g.drawImage(background,0,0,this);
		}
	}
}
