在Java中自由块的执行顺序

father.java

public class father {

    static{//静态块
       System.out.println("father'sSTATIC free block running");
    }

    {//非静态块
 System.out.println("father'sfree block running");
    }

    public father(){

       System.out.println("father'sconstructor running");

    }
}

son.java
public class son extends father{
    static{//静态块
       System.out.println("son'sSTATIC free block running");
    }

    {//非静态块
       System.out.println("son's freeblock running");
    }

    public son() {
       // TODO Auto-generated constructor stub
       System.out.println("son'sconstructor running");
    }
}

test.java

public class test{

      public static void main(String[] args) {

       Class f;

       try {

           System.out.println("--------beforeload father--------");

           f=Class.forName("freeblock.father");

           System.out.println("--------afterload father---------");        

           System.out.println("--------beforeinitial father object--------");

           f.newInstance();

           System.out.println("--------afterinitial father object--------");

       } catch (ClassNotFoundException e) {

           e.printStackTrace();

       } catch (InstantiationException e) {
           e.printStackTrace();

       } catch (IllegalAccessException e) {

           e.printStackTrace();
       }     
       Class s;

       try {
