Looking for a way to write a BufferedImage to a file

Question

i am currently working with images and transforming them. the image is stored as a BufferedImage object and i was wondering if anybody knows how to write the image back as a new file after its been modified.
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.ImageIcon;
import javax.swing.JSlider;
import javax.swing.event.ChangeListener;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.BorderLayout;
import java.awt.image.BufferedImage;
public class ExampleFramework extends JPanel {
private BufferedImage originalImage;
private BufferedImage filteredImage;
private JSlider slide = new JSlider(1, 50, 25);
private int height, width;
ExampleFramework(String titlebar) {
createBufferedImages();
setUpJFrame(titlebar);
private void createBufferedImages() {
Image image =
new ImageIcon("test.jpg").getImage();
height = image.getHeight(null);
width = image.getWidth(null);
originalImage =
new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
filteredImage = new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
Graphics g = originalImage.createGraphics();
g.drawImage(image, 0, 0, null);
g.dispose();
this class is not complete but it should give you an idea of the problem am having. there are 2 buffered images and all am looking for is a way to write the contents of the bufferedimage to a file

Answer 1

First, I get rid of Image:
private void createBufferedImages() {
    BufferedImage image = ImageIO.read(new File("test.jpg"));
    int targetType = BufferedImage.TYPE_INT_RGB;
    originalImage = convertType(image, targetType);
    filteredImage = new BufferedImage(image.getWidth(), image.getHeight(), targetType);
static BufferedImage convertType(BufferedImage src, int targetType) {
    if (src.getType() == targetType)
        return src;
    BufferedImage tgt = new BufferedImage(src.getWidth(), src.getHeight(), targetType);
    Graphics2D g = tgt.creategraphics();
    g.drawRenderedImage(src, null);
    g.dispose();
    return tgt;
}(I don't know how important type RGB is to you, so I put in a convert routine.
If these images are primarily for viewing, I would make them compatible
with the screen by using method createCompatibleImage.
As for writing an image, it can be one line of code:
imageIO.write(bufferedImage, "jpeg", file);See ImageIO[url].
