Thank you for your contribution.
You don't need to manually implement sorting algorithms these days in most cases, you can use the Arrays.sort or Collections.sort with a custom comparator. e.g. https://www.google.com/search?q=java+custom+sort+comparator+collections&oq=java+custom+sort+comparator+collections&aqs=chrome..69i57j0.6234j0j7&sourceid=chrome&ie=UTF-8
Bubble sorting is inefficient (only for teaching, not for practical use), if you really want to go down implementing your sorting algorithm, choose "selection sort" in simple sorting, and "quick-sort" or "merge-sort" if you want some more complex ones.
No unit tests.
