Answer 1

First get the entry set from the map:

Set> entries = map.entrySet();

Now dump that into an ArrayList so you can sort it:

List> sortedEntries = new ArrayList<>(entries);

Now sort the list:

Collections.sort(sortedEntries, /*Define your comparitor here to compare by values */);

Your list now has the contents of the map sorted by value, you can access them in whatever order you like.
