e358. Creating a Sorted SetA sorted set is a set that maintains its elements 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 e352 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()]);
