如何从Java传递Scala枚举

我有一个Scala/Java双语言项目，需要从Java传递Scala枚举

object MonthSelection extends Enumeration {
   type MonthSelection = Value

   val LastMonth, ThisMonth, NextMonth, CustomMonth = Value
}

class MyClass {

   def doDateStuff(monthChosen: MonthSelection) = {
   // do stuff
   }
}

我如何从Java中调用它？由于似乎无法导入scala.Enumeration.Value，因此出现编译错误

   MyClass myClass = new MyClass();
   myClass.doStuff(MonthSelection.ThisMonth);

---

如果有疑问，请查看生成的字节码。：）

好的，简单。所有这些枚举都是公共静态方法。我只需要导入scala.Enumeration并直接调用这些方法

$> cat Some.java
import scala.Enumeration;

public class Some {
    public static void main(String args[]) {
        System.out.println("Hello!");
        System.out.println(MonthSelection.CustomMonth());
    }
}

$> javac -cp $SCALA_HOME/lib/scala-library.jar:bin/ -d bin Some.java
$> ls bin
MonthSelection$.class  MonthSelection.class  Some.class
$> java -cp $SCALA_HOME/lib/scala-library.jar:bin Some              
Hello!
CustomMonth

希望这能给你提供更多的想法。：）

$> cat Some.java
import scala.Enumeration;

public class Some {
    public static void main(String args[]) {
        System.out.println("Hello!");
        System.out.println(MonthSelection.CustomMonth());
    }
}

$> javac -cp $SCALA_HOME/lib/scala-library.jar:bin/ -d bin Some.java
$> ls bin
MonthSelection$.class  MonthSelection.class  Some.class
$> java -cp $SCALA_HOME/lib/scala-library.jar:bin Some              
Hello!
CustomMonth
