Java虚拟机在载入类的时候。先初始化父类静态变量。再初始化子类静态变量。然后载入父类，最后载入子类

public class Parent {



static{

System.out.println("static parent");

}



public Parent(){

System.out.println("parent loaded");

}



public void getaaa(){

System.out.println("parent aaa");

}

}

public class Child extends Parent{



public Child(){

System.out.println("child load");

}



public void getaaa(){

System.out.println("child aaa");

}



static{

System.out.println("static child");

}



public static void main(String[] args){

Child child = new Child();

child.getaaa();

}

}

结果  ：

static parent

static child

parent loaded

child load

child aaa
