10天学完java基础-链表

1.单项链表---打印火车

//定义火车节点class Node{private String data = null ;Node node = null ;public Node(String data){this.data = data ;}public void setNode(Node node){this.node = node ;}public Node getNode(){return this.node ;}public String getData(){return this.data ;}}public class LinkDemo01{public static void main(String args[]){Node root = new Node("火车头") ;Node n1 = new Node("火车A") ;Node n2 = new Node("火车B") ;Node n3 = new Node("火车C") ;root.setNode(n1) ;n1.setNode(n2) ;n2.setNode(n3) ;printNode(root) ;}//打印火车public static void printNode(Node node){System.out.println(node.getData() + "\t") ;if(node.getNode() != null){printNode(node.getNode()) ;}}}
