title: Any implementation of Ordered Set in Java?
body: <p>If anybody is familiar with Objective-C there is a collection called <a href="https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSOrderedSet_Class/index.html"><code>NSOrderedSet</code></a> that acts as <strong>Set</strong> and its items can be accessed as an <strong>Array</strong>'s ones.</p>
  
  <p>Is there anything like this in Java?</p>
  
  <p>I've heard there is a collection called <a href="http://docs.oracle.com/javase/8/docs/api/java/util/LinkedHashMap.html"><code>LinkedHashMap</code></a>, but I haven't found anything like it for a set.</p>
