Question concerning writing image as JPG using imageio

Here's the code that I'm using:

Iterator writers = ImageIO.getImageWritersByFormatName("jpg");
ImageWriter writer = (ImageWriter)writers.next();
ImageOutputStream ios = ImageIO.createImageOutputStream(new
File(outputFile));
writer.setOutput(ios);
writer.write(outputImage);

I'm wondering about the quality of the output image (i.e how much data
is lost), and is there a way to change it?

this is java , what do you think?

have a look at:

JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(os);
JPEGEncodeParam param =
encoder.getDefaultJPEGEncodeParam(outImage);

param.setQuality((float) .9, false);
encoder.setJPEGEncodeParam(param);
encoder.encode(outImage);
