title: Sort map in descending order java8
body: <pre><code>private static &lt;K, V extends Comparable&lt;? super V&gt;&gt; Map&lt;K, V&gt;
      sortByValue( Map&lt;K, V&gt; map )
      {
          Map&lt;K, V&gt; result = new LinkedHashMap&lt;&gt;();
          Stream&lt;Map.Entry&lt;K, V&gt;&gt; st = map.entrySet().stream();
  
          st.sorted( Map.Entry.comparingByValue() )
                  .forEachOrdered( e -&gt; result.put(e.getKey(), e.getValue()) );
  
          return result;
      }
  </code></pre>
  
  <p>This is an example from <a href="https://stackoverflow.com/questions/109383/sort-a-mapkey-value-by-values-java?page=1&amp;tab=votes#tab-top">this</a> post. It works. the problem is that it sorts in ascending order. How can I change it to descending ?</p>
  
  <p>I can do that like this:</p>
  
  <pre><code>public static &lt;K, V extends Comparable&lt;? super V&gt;&gt; Map&lt;K, V&gt;
  sortByValue( Map&lt;K, V&gt; map )
  {
      List&lt;Map.Entry&lt;K, V&gt;&gt; list =
              new LinkedList&lt;Map.Entry&lt;K, V&gt;&gt;( map.entrySet() );
      Collections.sort( list, new Comparator&lt;Map.Entry&lt;K, V&gt;&gt;()
      {
          public int compare( Map.Entry&lt;K, V&gt; o1, Map.Entry&lt;K, V&gt; o2 )
          {
              return (o2.getValue()).compareTo( o1.getValue() );//change o1 with o2
          }
      } );
  
      Map&lt;K, V&gt; result = new LinkedHashMap&lt;K, V&gt;();
      for (Map.Entry&lt;K, V&gt; entry : list)
      {
          result.put( entry.getKey(), entry.getValue() );
      }
      return result;
  }
  </code></pre>
  
  <p>I can do that by changing order i this line: <code>return (o2.getValue()).compareTo( o1.getValue() );</code> But I would like to try with lambda expr.</p>
