title: What is the equivalent lambda expression for System.out::println
body: <p>I stumbled upon the following Java code which is using a method reference for <code>System.out.println</code>:</p>
  <pre><code>class SomeClass {
      public static void main(String[] args) {
             List&lt;Integer&gt; numbers = Arrays.asList(1,2,3,4,5,6,7,8,9);
             numbers.forEach(System.out::println);
          }
      }
  }
  </code></pre>
