问题:

Is it correct that if we have a BufferedImage object in java, we could potentially write it out in ANY format using ImageIO.write (if we have a Writer object for the same)? I tried writing a BufferedImage object into a jpg file, it outputted an empty image file however when i tried writing it in to a png file, it worked fine.

A BufferedImage can be written into any format that ImageIO.write supports (that is, has an ImageWriter available), yes. Please show the code if you can't get it to work.
