In this video I introduce the idea collections of objects using a dynamic data structure in Java called the ArrayList. I show how to create a standard array of String objects and how to iterate over the array to print out the array items. I then replace this standard array with an ArrayList and show how String object can added, removed and how we can iterate over the ArrayList to print out the items it contains.
