Creating a Sorted Set
A sorted set is a set that maintains its items in a sorted
order. Inserts and retrievals are more expensive in a sorted set but
iterations over the set is always in order.
See also Creating a Set.
// Create the sorted set
SortedSet set = new TreeSet();
// Add elements to the set
set.add("b");
set.add("c");
set.add("a");
// Iterating over the elements in the set
Iterator it = set.iterator();
while (it.hasNext()) {
// Get element
Object element = it.next();
}
// The elements are iterated in order: a, b, c
// Create an array containing the elements in a set (in this case a String array).
// The elements in the array are in order.
String[] array = (String[])set.toArray(new String[set.size()]);
