Scrolling BufferedImage Java

Question

I'm making a simple side scroller game in Java but am having trouble making the camera move with the person. My plan was to create a buffered image that could adjust the region of the image that is displaying and simply have it follow my character. However, I couldn't find any functions in the API to change the region of the buffered image that's displayed, so how could I do this? Thanks for any help provided.

 //The level is created in an 800x400 pixel size, is there any way I can change
 //the region myImage displays?
myImage =  new BufferedImage(400, 400, BufferedImage.TYPE_INT_RGB);

Well while you will be drawing your image you have a lot of options for example this function can draw any rectangle from your original image on any rectangle of the surface you get Graphics object from.

@user3050810 Well for example if you'll override paint or paintComponent method you will be getting Graphics g as it's argument, then you can call something like g.drawImage (myImage, 0, 0, 400, 400, x, 0, x + 400, 400, null); it will draw the rectangle 400x400 from myImage with offset x on component you've overridden method from. If you want to draw on some images just get Graphics with createGraphics function and so on.
