From source file:Main.java

public static void main(String[] argv) throws Exception {
    SortedSet<String> set = new TreeSet<String>();
    set.add("b");
    set.add("c");
    set.add("a");

    Iterator it = set.iterator();
    while (it.hasNext()) {
        Object element = it.next();
    }/*w ww  .j  a  va  2s .  c o  m*/
    String[] array = (String[]) set.toArray(new String[set.size()]);
}
