Rotating Images with Java 2D

Question

Im working on a program that requires the use of rotating images. I am using AffineTransformation to rotate and translate my BufferedImages. I have a problem when I rotate, I have a picture posted bellow of sample code and it's output.

I four images, back (a solid color background, will not be solid in final product); tread and base, both get rotated together; and top, which rotates seperatly from the others.
My problem is that when an image is rotated, it takes a section of the background with it even though its a seperate image. Im wondering how to fix or get around this problem. Sorry if this is a dumb question but I would really like to get this down.
Thanks.

Answer 1

alright sorry, I didnt think that I needed to paste the whole code. Anyway I tried it out on some other computers and it didnt have this problem, both computers I used had java 6.0 and mine has 5.0 (Im pretty sure) so maybe thats the problem, but anyway I would still like to figure it out for this computer.
heres the code for the paintPanel, the program that runs it just adds it as a panel then sends arguments into the Overpaint method.
import java.awt.image.BufferedImage;
import javax.swing.*;
import java.io.*;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.geom.*;
public class TankPaint extends JPanel
  static BufferedImage back;
  private BufferedImage top,base,tread;
  private Graphics g;
  private int x,y,x2,y2,deg1,deg2;
  //boolean dialog = false;
     public TankPaint(String back,String top,String base,String tread,int deg1,int deg2,int x,int y,int x2,int y2)
          super();
          try
               this.back = ImageIO.read(new File("Backgrounds\\"+back));
               this.top = ImageIO.read(new File("Images\\"+top));
               this.base = ImageIO.read(new File("Images\\"+base));
               this.tread = ImageIO.read(new File("Images\\"+tread));
          catch (IOException ex) {}
          this.x = x;
          this.y = y;
          this.x2 = x2;
          this.y2 = y2;
          this.deg1 = deg1;
          this.deg2 = deg2;
     public void paintComponent(Graphics g)
      Graphics2D g2d = (Graphics2D)g;
     AffineTransform transform = new AffineTransform();
          g2d.setColor(Color.red);
         g.drawImage(back, x2, y2, this);
         //g.drawImage(tread, x-125, y-125, this);
             //g.drawImage(base, x-125, y-125, this);
             //g.drawImage(top, x-125, y-125, this);
          transform.setToTranslation(x,y-5);
          transform.rotate(Math.toRadians(deg1),tread.getWidth()/2,tread.getHeight()/2-10);
         g2d.drawImage(tread, transform, this);
             g2d.drawImage(base, transform, this);
          transform.setToTranslation(x,y);
          transform.rotate(Math.toRadians(deg2),top.getWidth()/2,top.getHeight()/2-25);
             g2d.drawImage(top, transform, this);
  public void overPaint(String back,String top,String base,String tread,int deg1,int deg2,int x,int y,int x2,int y2)
     try
          this.back = ImageIO.read(new File("Backgrounds\\"+back));
          this.top = ImageIO.read(new File("Images\\"+top));
          this.base = ImageIO.read(new File("Images\\"+base));
          //this.tread = ImageIO.read(new File("Images\\"+tread));
     catch (IOException ex) {System.out.println("Image Error");}
       this.x = x;
    this.y = y;
    this.x2 = x2;
    this.y2 = y2;
    this.deg1 = deg1;
     this.deg2 = deg2;
     repaint();
}
