title: How to eliminate duplicates in Guava MultiMap values?
body: <p>Code:</p>
  
  <pre><code>    Multimap&lt;String, String&gt; myMultimap = ArrayListMultimap.create();
      myMultimap.put("12345", "qwer");
      myMultimap.put("12345", "abcd");
      myMultimap.put("12345", "qwer");
      System.out.println(myMultimap);
  </code></pre>
  
  <p>Result:</p>
  
  <pre><code>{12345=[qwer, abcd, qwer]}
  </code></pre>
  
  <p>Is it possible to eliminate duplicate "qwer" ?
  Thanks.</p>
