TreeSet treeset = new TreeSet();
// Create new element object and Add the elementreeset to the set:
treeset.add(new Integer(2));
treeset.add(new Integer(5));
treeset.add(new Integer(7));
System.out.println("treeset = " + treeset);
System.out.println("All elements os th set ...");
Iterator i = treeset.iterator();
