节点类的泛型定义(数据结构)

public class Node<T>{//节点类的泛型定义
        T data;//数据域
        Node<T> next;//指针域
        public Node(Node<T>n){
            next = n;
        }
        public Node(T obj,Node<T>n){
            data = obj;
            next = n;
        }
        public T getData(){
            return data;
        }
        public Node<T> getNext(){
            return next;
        }
    }
