你真的会用ABAP, Java和JavaScript里的constructor么?

如果constructor里调用了一个成员方法，这个方法被子类override了，当初始化一个子类实例时，父类的构造函数被的调用，此时父类构造函数的上下文里调用的成员方法，是父类的实现还是子类的实现？
你能不用运行代码，就能准确说出这些语句会打印什么出来呢？

ABAP

class ZCL_SUPER definition public  create public .public section.  methods CONSTRUCTOR .  methods SET_I    importing      !IV_I type INT4 .protected section.private section.  data MV_SUPER type INT4 .ENDCLASS.CLASS ZCL_SUPER IMPLEMENTATION.  method CONSTRUCTOR.    me->set_i( 100 ).  endmethod.  method SET_I.    me->mv_super = iv_i.  endmethod.ENDCLASS. class ZCL_SUB definition public  inheriting from ZCL_SUPER  final  create public .public section.  methods PRINT .  methods SET_I    redefinition .protected section.private section.  data MV_SUB type I value 1 ##NO_TEXT. ENDCLASS.CLASS ZCL_SUB IMPLEMENTATION.  method PRINT. WRITE: / ' sub:' , mv_sub.  endmethod.  METHOD set_i. super->set_i( iv_i = iv_i ).    me->mv_sub = iv_i. WRITE: / 'mv_sub assigned by: ' , iv_i.  ENDMETHOD.ENDCLASS. 

测试：

NEW zcl_sub( )->print( ). 

测试结果：sub: 1

Java

public class SuperClass { private int mSuperX; public SuperClass() {        setX(99);    } public void setX(int x) {        mSuperX = x;    }} public class SubClass extends SuperClass { private int mSubX = 1; public SubClass() {} @Override public void setX(int x) { super.setX(x);        mSubX = x;        System.out.println("SubX is assigned " + x);    } public void printX() {        System.out.println("SubX = " + mSubX);    }} 

test:

public static void main(String[] args) {        SubClass sc = new SubClass();        sc.printX();    }
