Unbuffered image to .jpg

Question

I am using a Java bean that the developer said that they would pass me an unbuffered image and to use awt to convert that into a .jpg image. I am having a hard time understanding how to access the unbuffered image and then what to do with it. I know this is Java 101 but can someone give me some pointers? Thanks

hi
below is a simple method which takes Image object as parameter,
converts it into buffered image , also converts it into jpg image and saves it to hard disk.
this might help you.
public void save(Image img)
BufferedImage bi = new BufferedImage(
img.getWidth(null),
img.getHeight(null),
BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = bi.createGraphics();
g2.drawImage(img, null, null);
FileOutputStream out = null;
try
out = new FileOutputStream("c:/temp/one.jpg");
catch (java.io.FileNotFoundException io)
System.out.println("File Not Found");
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi);
param.setQuality(0.5f,false);
encoder.setJPEGEncodeParam(param);
try
encoder.encode(bi);
out.close();
catch (java.io.IOException io)
System.out.println("IOException");
