public interface A {
void hello() {
System.out.println("Hello from A");
}
}
public interface B {
void hello() {
System.out.println("Hello from B");
}
}
public class C implements B, A { }


should be


public interface A {
default void hello() {
System.out.println("Hello from A");
}
}
public interface B {
default void hello() {
System.out.println("Hello from B");
}
}
public class C implements B, A { }
