graphx samples in Java

[David Soroko]

Hi

Where can I find the equivalent of the graphx example 
(http://spark.apache.org/docs/0.9.0/graphx-programming-guide.html#examples ) in 
Java ? For example. How does the following translates to Java


val users: RDD[(VertexId, (String, String))] =

  sc.parallelize(Array((3L, ("rxin", "student")), (7L, ("jgonzal", "postdoc")),

                       (5L, ("franklin", "prof")), (2L, ("istoica", "prof"))))





thanks
