  public static void main(String[] args) {
    //creating a list object
    List<Integer> MyList = new ArrayList<Integer>();

    //populating the list
    MyList.add(10);
    MyList.add(20);
    MyList.add(30);
    MyList.add(40);

    //printing the list
    System.out.println("MyList contains: " + MyList); 

    //creating an synchronized view of the list
    List NewList = Collections.synchronizedList(MyList);

    //printing the synchronized list
    System.out.println("NewList contains: " + NewList); 
  }
