How I am supposed to translate this spark scala line to java

Question

I am trying out spark-neo4j connector . In examples of this link, I found following line:

neo.cypher("MATCH (n:Person) RETURN id(n)").loadRdd[Long].mean

I am trying to convert this line to Java equivalent. But I am not getting how should I proceed for lack of my understanding of scala. The issue is with loadRdd[Long] .

Answer 1

我对Spark不太了解，但是我希望Java是：

neo.cypher("MATCH (n:Person) RETURN id(n)").<long>loadRdd().mean()
