How do you call a Scala singleton method from Java?

Question

I\'m trying to inject some Scala code into my existing Java app. (So, being said, I want some more fun).

I create a singleton stuff in Scala

ScalaPow

What were the errors you were getting? Using your Scala sample and the following Java class:

cat test.java:

import org.fun.*;

public class test {
    public static void main(String args[]) {
       System.out.println("show my power: " + ScalaPower.showMyPower(3));       
    }
}

And running it as follows:

java -cp .:<path-to/scala/install-dir>/lib/scala-library.jar test

gives my the output:

show my power: 0, 1, 2
