public static void main(String[] args) {
TreeSet<String> cars = new TreeSet<String>();
cars.add("Volvo");

cars.add("Ford");
cars.add("Mazda");

}
}Definition and Usage
The descendingSet() method returns the items of the set in reverse (descending) order, from the last (highest) item to the first (lowest) item.
The returned set is a view of the original set (it shows the same items, it is not a copy). If you change one of them, the other one changes too.
Syntax
public NavigableSet<T> descendingSet()T refers to the data type of items in the set.
