Is there any way i could find out the
extension and mimtype from stream(or uploaded file)?
is = dataHandler.getInputStream();
bi = ImageIO.read(is);
System.out.println("width: " + bi.getWidth());
System.out.println("height: " + bi.getHeight());
System.out.println("type" + bi.getType());
I can use the Magic.getMagicmatch to get the mime type?
mimeType = Magic.getMagicMatch(BYTESTREAM, false).getMimeType();
but, is there any way to get the extension from uploaded file using

Use String's lastIndexOf method to find the last location of a dot, then return the substring from that location + 1. Be careful that lastIndexOf will return -1 when no dot is found, which also means there is no extension.
