JDK8如何用::关键字调用有参构造

Question

JDK8用::关键字调用无参构造是::new,请问用::调用有参构造是怎样写?

// 默认调用无参构造
Something s = Something::new;
// 如何调用有参构造
Something s = Something::???;

一样的

    public static void main(String[] args) {
        Function<String, Test2> f = Test2::new;
        BiFunction<String, String, Test2> f2 = Test2::new;
    }

    public static class Test2 {

        public Test2(String s) {

        }

        public Test2(String s1, String s2) {

        }
    }
