简单的单向链表:

class Node{private String data;private Node next;public Node(String data){this.data=data;}public String getData(){return this.data;}public void setNext(Node next){this.next=next;}public Node getNext(){return this.next;}public void addNode(Node newNode){if(this.next==null){this.next =newNode;}else{this.next.addNode(newNode);}}public void printNode(){System.out.println(this.data);if(this.next !=null){this.next.printNode();}}}class Link{private Node root;public void add(String data){if(data==null){return;}Node newNode= new Node(data);if(this.root==null){this.root=newNode;}else{this.root.addNode(newNode);}}public void print(){if(this.root!= null){this.root.printNode();}}}public class Day {         public static void main(String args[]) {        Link all =new Link();all.add("1");all.add("2");all.add("3");  all.add("4");all.add("5");all.print();}              }验证通过.

继承的一个简单模型":

class Person{private String name;private int age;public void setName(String name){this.name=name;}public String getName(){return this.name;}public void setAge(int age){this.age=age;}public int getAge(){return this.age;}}class Student extends Person{private String school;public void setSchool(String school){this.school=school;}public String getSchool(){return this.school;}}public class Day {         public static void main(String args[]) {      Student stu=new Student();  stu.setName("heyao");  stu.setAge(22);  stu.setSchool("Central South University");  System.out.println(stu.getName()+">>>>>"+stu.getAge()+">>>>>>"+stu.getSchool());}              }
