高分散了啊，大家帮忙呀

我曾经看过一本书上这样写的：
class Node{
public Node Next;
public Object Value;
public Node(object value);this(value,null){}
public Node(object value,Node next){Next=next;
Value=value;}
}
}
我不知道这段代码public Node Next 声明是否错误？为什么？

no error here, it is just a reference, not a copy of an object, which points to the next node

in C++, this would look like

class Node{
public:
Node* Next;
Object* Value;
//...
};

which is perfectly normal
