构造代码块、静态代码块、构造方法的执行顺序

public class ClassA {
    public ClassA(){
        System.out.println("construct ClassA");
    }
    static {
        System.out.println("Class A");
    }
    {
        System.out.println("in ClassA");
    }
}
public class ClassB extends ClassA{
    public ClassB(){
        System.out.println("construct ClassB");
    }
    static {
        System.out.println("Class B");
    }
    {
        System.out.println("in ClassB");
    }
    public static void main(String[] args) {
        new ClassB();
    }
}
