java中对象的初始化过程

class Parent{
    int num = 8;// ->3
    Parent(){
       //super();  // ->2
       //显示初始化   // ->3
       //构造代码段   // ->4
       show(); // ->5
    }
     
    {//  ->4
        System.out.println("Parent constructor code run->");
    }
     
    public void show(){//被覆盖
        System.out.println("num = " + num);
    }
}
 
class Child extends Parent{
    int num = 9;// ->6
     
    Child(){
         super();// ->1
         //显示初始化  ->6
         //构造代码段  ->7
         num = 10; // ->8
         System.out.println("after Child constructor code && Child constructor num = " + num);// ->9
    }
     
    {// ->7
       System.out.println("Child constructor code run->");
       System.out.println("after Child constructor num = " + num);
    }
     
    public void show(){
        System.out.println("num = " + num);
    }
}
 
public class PC{
     public static void main(String[] args){
         new Child();
     }
}
