+Java 8+ users can also possibly write the above `FlatMapFunction` in a
more concise way using
+lambda expression as follows:
+
+{% highlight java %}
+JavaRDD<String> words = lines.flatMap(s -> Arrays.asList(s.split(" ")));
+{% endhighlight %}

+Same possibility applies to all passed in anonymous classes in java 8.

Nit, but maybe say: "This lambda syntax can be applied to all anonymous
classes in Java 8".
