类加载执行顺序

听了好久的类加载执行顺序，自己一直没有实践过，今天休息时想到这个问题，亲自动手验证如下：

上代码

public class Domain {

    public Domain(String str){
        System.out.println(str);
    }
}


public class SuperClass {

    private static Domain d1 = new Domain("father static member variable");

    private Domain d2 = new Domain("father common member variable");

    static{
        System.out.println("father static code block");
    }

    {
        System.out.println("father dynamic code block");
    }

    SuperClass(){
        System.out.println("father no arguments constructor");
    }

}


public class SubClass extends SuperClass {

    private static Domain d1 = new Domain("child static member variable");

    private Domain d2 = new Domain("child common member variable");

    static {
        System.out.println("child static code block");
    }

    {
        System.out.println("child dynamic code block");
    }


    public SubClass(){
        System.out.println("child no arguments constructor");
    }public static void main(String[] args){
            SubClass t1 = new SubClass();
    }
}

以上三个类，SubClass继承自SuperClass，Domain为测试用的类。执行结果如下：
