1.  object CollectionConverters extends DecorateAsJava with DecorateAsScala
2.  object OptionConverters

   This object provides extension methods that convert between Scala Option and Java Optional types.

   This object provides extension methods that convert between Scala Option and Java Optional types.

   Scala Option is extended with a toJava method that creates a corresponding Optional, and a toJavaPrimitive method that creates a specialized variant (e.g., OptionalInt) if applicable.

   Java Optional is extended with a toScala method and a toJavaPrimitive method.

   Finally, specialized Optional types are extended with toScala and toJavaGeneric methods.

   Example usage:

   import scala.jdk.OptionConverters._
   val a = Option("example").toJava      // Creates java.util.Optional[String] containing "example"
   val b = (None: Option[String]).toJava // Creates an empty java.util.Optional[String]
   val c = a.toScala                     // Back to Option("example")
   val d = b.toScala                     // Back to None typed as Option[String]
   val e = Option(2.7).toJava            // java.util.Optional[Double] containing boxed 2.7
   val f = Option(2.7).toJavaPrimitive   // java.util.OptionalDouble containing 2.7 (not boxed)
   val g = f.toScala                     // Back to Option(2.7)
   val h = f.toJavaGeneric               // Same as e
   val i = e.toJavaPrimitive             // Same as f
