<p>I know about <a href="https://docs.oracle.com/javase/9/docs/api/java/util/SortedSet.html" rel="noreferrer"><code>SortedSet</code></a>, but in my case I need something that implements <code>List</code>, and not <code>Set</code>. So is there an implementation out there, in the API or elsewhere?</p>

<p>It shouldn't be hard to implement myself, but I figured why not ask people here first?</p>

Why not encapsulate a set with a list, sort like:
```
```
new ArrayList( new LinkedHashSet() )
```
```
This leaves the other implementation for someone who is a real master of Collections ;-)
