Convert a Scala Option[java.lang.Double] to a Java OptionalDouble

Convert a Scala Option[java.lang.Double] to a Java OptionalDouble

Note: this method uses the boxed type java.lang.X instead of the primitive type scala.X to improve compatibility when using it in Java code (the Scala compiler emits C[Int] as C[Object] in bytecode due to scala/bug#4214). In Scala code, add import scala.jdk.OptionConverters._ and use the extension methods instead.

Convert a Scala Option[java.lang.Integer] to a Java OptionalInt

Convert a Scala Option[java.lang.Integer] to a Java OptionalInt

Note: this method uses the boxed type java.lang.X instead of the primitive type scala.X to improve compatibility when using it in Java code (the Scala compiler emits C[Int] as C[Object] in bytecode due to scala/bug#4214).

Convert a Scala Option[java.lang.Long] to a Java OptionalLong

Note: this method uses the boxed type java.lang.X instead of the primitive type scala.X to improve compatibility when using it in Java code (the Scala compiler emits C[Int] as C[Object] in bytecode due to scala/bug#4214).
