What is the preferred approach to add elements to a Collection?

Using constructor
Using add method
Using Collections.addAll method
Using set method

The correct answer is: Using Collections.addAll method

The preferred approach to add elements to a Collection is by using the Collections.addAll method. This is because this method offers increased performance by allowing multiple elements to be added at once. Additionally, the constructor option only allows for one element to be added at a time, and the add and set methods can result in duplicate elements being added to the Collection. Therefore, the Collections.addAll method is the most efficient and effective way to add multiple elements to a Collection.
