Convert Scala Option to Java Optional

Question

I need to convert Scala Option to Java Optional. I managed to wrote this:

public  Optional convertOption2Optional(Option option) {
           


        

Answer 1

The shortest way I can think of in Java is:

Optional.ofNullable(option.getOrElse(null))

@RégisJean-Gilles actually suggested even shorter if you are writing the conversion in Scala:

Optional.ofNullable(option.orNull)

By the way you must know that Scala does not support Java 8 until Scala 2.12, which is not officially out yet. Looking at the docs (which may change until the release) there is no such conversion in JavaConversions.
