Which set modifications enable the code to compile and run?

Answer: ?
line n1:
– import facades.Foo; //or facades.*;
– import facades.Boo;
line n2:
import facades.*;
import org.domain.Woofy;

Code question:
package facades;

public interface Foo {

}
package facades;

public interface Boo extends Foo { //interface Boo implements interface Foo??

}
package org.domain;
import facades.Foo; //or facades.*;
import facades.Boo;

public class Woofy implements Boo, Foo {

}
package org;
import facades.*;
import org.domain.Woofy;

public class Test {

public static void main(String[] args) {
Foo obj = new Woofy();
System.out.println(obj.getClass());

}

}
Output:
class org.domain.Woofy
