title: Print HashMap Values with Stream api
body: <pre><code>HashMap&lt;String, Double&gt; missions = new HashMap&lt;&gt;();
  missions.put("name", 1.0);
  missions.put("name1", 2.0);
  missions.keySet().stream().forEach(el-&gt; System.out.println(el));
  </code></pre>
  
  <p>This prints only the keys, how do I print the map's values instead?</p>
