Demo Project using Collection Activities

Below, you will find the video link of a demo about these activities to understand them in a better manner. First, we will create an ArrayList using the Create a collection activity. Next, we will see how we can add an item to the collection. Then, we will check whether an item exists in that collection. If the item does exist, it should first remove that particular item. Then, it should loop through the collection and display the remaining items of the collection. Whereas, if the item does not exist, it should just display a message saying, “item does not exist”.
