在java调用构造函数

class A {

    A() {
        System.out.print("A");
    }
}

class B extends A {
     B() {
        System.out.print("B");
    }
}

class C extends B {
 C() {
        System.out.print("C");
    }
}

public class My extends C {
My(){
super();
}
    public static void main(String[] args) {
        My m = new My();
    }
}

问题从一个面试问题开始(用 Java 创建对象时会发生什么?)

Question starts from one Interview Question (what happens when an object is created in Java?)

答案是...

调用最派生类的构造函数.第一个构造函数所做的事情是为其调用构造函数超类.这个过程一直持续到构造器java.lang.Object 被调用，因为 java.lang.Object 是java中的所有对象.在构造函数体执行之前，所有实例变量初始化器和初始化块都是执行.然后执行构造函数的主体.因此，基类的构造函数首先完成，而基类的构造函数完成大多数派生类最后完成.

The constructor for the most derived class is invoked. The first thing a constructor does is call the consctructor for its superclasses. This process continues until the constrcutor for java.lang.Object is called, as java.lang.Object is the base class for all objects in java. Before the body of the constructor is executed, all instance variable initializers and initialization blocks are executed. Then the body of the constructor is executed. Thus, the constructor for the base class completes first and constructor for the most derived class completes last.

所以，根据上面的说法，答案应该是ABCC，但它只显示ABC.虽然，当我在派生构造函数中注释 super() 时.然后，输出是ABC.请帮我弄清楚，我是否误解了上面的段落.?

So, according to above statement, answer should be ABCC, but it showing only ABC. Although, when i'm commenting the super() in derived constructor. Then, output is ABC. Please, help me to figure out, did i misunderstand the above paragraph. ?
