public class Main {

    public static void main(String[] args) {

        System.out.println("A");

        new Main();

        new Main();

    }

    public Main() {

        System.out.println("B");

    }

    {

        System.out.println("C");

    }

    static {

        System.out.println("D");

    }

}

以上程序输出的结果，正确的是？()
