	arrayList.add(2,31);
    System.out.println("Current Array List"+arrayList);
    
    arrayList.remove(0);
    System.out.println("Array List after removing 1st Index element");
    for (Integer arrayElement : arrayList) {
    	 System.out.println("Element is " +arrayElement);
    }
    arrayList.remove(1);
