What interface in Java can I use to store unique objects?
<p>I need to create a class that will store a unique object elements. I don't need to sort these elements but they must be unique. </p>

<p>Can someone give me advice as to what interface I should be using? It was suggested to me by one person that I could use Set and then another person said Vector or List. Now I am totally confused :-( </p>
