The Java SortedSet interface behaves like a normal Set with the exception that the elements it contains are sorted internally. Here is an example of iterating the elements of a the java.util.TreeSet class. The Java SortedSet interface has a method named subSet() method which will return Since all lists are already "sorted" by the order the items were added (FIFO ordering), you can "resort" them with another order, including the natural ordering of elements, using java.util.Collections.sort(). This can get rather computation heavy depending on your implementation and is pointless, unless you want to do it as an exercise, because of two main reasons: However, if you want to do it as an exercise here is a code sample to get you started, it uses the AbstractList abstract class: Note that if you haven't overridden the methods you need, then the default implementations from AbstractList will throw UnsupportedOperationExceptions. *; public class SortedSetTest { public static void main(String[] args) { // 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.ne. It also means you don't need to manually sort it. Example 1 import java.util.SortedSet; import java.util.TreeSet; public class JavaSortedSetheadSetExample1 { public static void main (String [] args) { SortedSet <Integer> object1 = new TreeSet<Integer> (); SortedSet <Integer> object2 = new TreeSet<Integer> (); object1.add (12); object1.add (13); object1.add (14); object1.add (15); object1.add (16); SortedSet would use the Comparable interface and its the compareTo () method to sort the String values.
