java 带静态域的导出类创建时都发生了什么？

先按从基类到导出类的顺序初始化静态域（之前已经初始化过的静态域不再初始化）

再按从基类到导出类的顺序初始化类，即基类普通字段+基类构造器主体+导出类字段+导出类主体...

package test;

class PrintInfo{
    static String Info(String s){
        System.out.println(s);
        return s;
    }
}
class grandfather{
    static String grandfatherstatic=PrintInfo.Info("grandfatherstatic1");
    static String grandfastatic2=PrintInfo.Info("grandfatherstatic2");
    String fa=PrintInfo.Info("grandfatherString1");
    String fa2=PrintInfo.Info("grandfatherString2");
    grandfather(){
        PrintInfo.Info("grandfatherconstructor");
    }
}
class father extends grandfather{
    static String fatherstatic=PrintInfo.Info("fatherstatic1");
    static String fastatic2=PrintInfo.Info("fatherstatic2");
    String fa=PrintInfo.Info("fatherString1");
    String fa2=PrintInfo.Info("fatherString2");
    father(){
        PrintInfo.Info("fatherconstructor");
    }

}
class son extends father{
    static String sonstatic=PrintInfo.Info("sonstatic1");
    static String sonstatic2=PrintInfo.Info("sonstatic2");
    String son=PrintInfo.Info("sonString1");
    String son2=PrintInfo.Info("sonString2");
    son(){
        PrintInfo.Info("sonconstructor");
    }
}
public class Test {
    public static void main(String[] args) {
        new son();
    }
}

output：

grandfatherstatic1
grandfatherstatic2
fatherstatic1
fatherstatic2
sonstatic1
sonstatic2
grandfatherString1
grandfatherString2
grandfatherconstructor
fatherString1
fatherString2
fatherconstructor
sonString1
sonString2
sonconstructor
