关于Java静态代码块、初始化块、构造函数的调用顺寻问题？

public class ClassA {

public ClassA(){
System.out.println("A 构造...");
}

{
System.out.println("this is A....");
}

static{
System.out.println("A static...");
}

}

public class ClassB extends ClassA{
public ClassB(){
System.out.println("B 构造...");
}

{
System.out.println("this is B....");
}

static{
System.out.println("B static...");
}

public static void main(String[] args) {
new ClassB();
}
}

A static...
B static...
this is A....
A 构造...
this is B....
B 构造...
