How do I construct a (non-static) Java inner class from Groovy

Question

If I have a class with an inner class like this:

public class A {
    class B { //note, no modifier on class or constructor
      B(String c) {System.out.println(c);}
    }
}

From Java (in the same package) I can do this:

public class C {
    public static void main(String[] args) {
        A a = new A();
        System.out.println(a. new B("test")); //crazy syntax!
    }
}

But in Groovy, that doesn't work. So how do I construct a new B [from a groovy class in the same package]?

Answer 1

I got it to work like this:

def a = new A()
A.B.newInstance(a, "foo")

And also like this:

def a = new A()
new A.B(a, "foo")

If the Java code is under your control rather than being an external library I'd far rather use a factory method, though.

Answer 2

try this

    A a = new A();
    System.out.println(new B(a, "test")); //crazy syntax!
