Using the add() Method: Adding Single Elements to a Set

You can also add elements to a set. To do this, there's a specific add() method. It's important to note that with this method, you can add only one element at a time. So, if you want to add 4 elements, for example, you'll need to use this method 4 times. Let's check out an example.
