Iterator iter1 = al.iterator();
while(iter1.hasNext()){
System.out.println(iter1.next());
}

Integer a[] = {1,2,3,4,5,6,7,8,9,10};
ArrayList X = new ArrayList(Arrays.asList(a));
ArrayList A = new ArrayList(Arrays.asList(1,2,3,4,5,6,7,8,9,10));
Vector B= new Vector(Arrays.asList(1,2,3,4,5,7,8,9,10));
