mjjaniec :
I need to convert Scala Option to Java Optional. I managed to wrote this:
public <T> Optional<T> convertOption2Optional(Option<T> option) {
return option.isDefined() ? Optional.of(option.get()) : Optional.empty();
}
But I don't like it.
Is there a simple way to do it, or a built-in scala converter? I'm looking for something like:
Options.asJava(option);
Dici :
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.
