How can I do this? | If you don't want duplicates in a `Collection`, you should consider why you're using a `Collection` that allows duplicates. The easiest way to remove repeated elements is to add the contents to a `Set` (which will not allow duplicates) and then add the `Set` back to the `ArrayList`:
