Empty Set doesn't exist

If you cant sense it, then it doesnt exist.

You cant see emptiness, therefore emptiness doesnt exist.

It's pretty much a no brainer to convert an exisiting list to a set. Seriously. All I would have to do is something like...

for(int i = 0; i < size; i++) {
    if(!newList.contains(data[i])) {
        newList.add(data[i]);
    }
}
