Answer 1

To change the solution in the link to sort by descending order, just reverse the condition:

...
// Note: this comparator imposes orderings that are inconsistent with equals.    
public int compare(String a, String b) {
    if (base.get(a) >= base.get(b)) {
        return 1; // For ascending, return -1;
    } else {
        return -1; // For ascending, return 1;
    } // returning 0 would merge keys
}
...
