Loop and remove element from a TreeSet

   

import java.util.Iterator;
import java.util.Set;
import java.util.TreeSet;

public class TreeSetExample {
  public static void main(String[] args) {
    // Create a new TreeSet
    Set<Integer> set = new TreeSet<Integer>();

    // Add Items to the TreeSet
    set.add(new Integer(1));
    set.add(new Integer(2));
    set.add(new Integer(3));
    set.add(new Integer(4));
    set.add(new Integer(5));
    set.add(new Integer(6));
    set.add(new Integer(7));
    set.add(new Integer(8));
    set.add(new Integer(9));
    set.add(new Integer(10));

    // Use iterator to display the vsetes
    System.out.println("TreeSet Before: ");
    for (Iterator i = set.iterator(); i.hasNext();) {
      Integer integer = (Integer) i.next();
      System.out.println(integer);
    }

    // Remove the integer 6
    System.out.println("
Remove Integer 6");
    set.remove(new Integer(6));

    // Use iterator to display the vsetes
    System.out.println("
TreeSet After: ");
    for (Iterator i = set.iterator(); i.hasNext();) {
      Integer integer = (Integer) i.next();
      System.out.println(integer);
