观察输出，总结。

class Grandparent {
    public Grandparent() {
        System.out.println("GrandParent Created");
    }
    public Grandparent(String string) {
        
        System.out.println("GrandParent Crented.String:"+string);
    }
}

class Parent extends Grandparent {
    public Parent() {
        //super("hello.Grandparent");
        System.out.println("Parent Created");
        //super("hello.Grandparent.");
    }

}

class Child extends Parent{
    public Child() {
        System.out.println("Child Created");
    }

}

public class Testlnherits {
    public static void main(String args[]) {
        Child c=new Child();
    }

}

输出结果：
GrandParent Created
Parent Created
Child Created
