I typed in "java jpeg quality" in Google and got a whole list of answers in a fraction of a second. This one looks useful:

The Java Developers Almanac - Compressing a JPEG File

It shows how you can set the compression quality when writing a JPEG with the Java ImageIO API.

What does or does not constitute high quality is of course a subjective notion.

Assuming that both images are of the same pixel size, and are in fact the very same image, then it is pretty safe to assume that the one that is larger in byte size has a higher quality.
