package com.jredu.oopch07;public class News {private String time;private String title;public News(String time,String title) {super();this.time = time;this.title = title;}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public String getTime() {return time;}public void setTime(String time) {this.time = time;}}

package com.jredu.oopch07;import java.util.ArrayList;import java.util.LinkedList;import java.util.List;public class Ch03 {public static void main(String[] args) {// TODO Auto-generated method stubList list = new LinkedList<>();News news1 = new News("2011-12-20", "三一重工续写神话");News news2 = new News("2011-12-20", "陈希慰问三一工作者");News news3 = new News("2011-12-20", "三一两项产品获评");News news4 = new News("2011-12-20", "把企业做强为区域发展献力");News news5 = new News("2011-12-20", "为成果而工作");News news6 = new News("2011-12-20", "天津6s中心获“用户满意服务明星称号”");//添加数据带集合list.add(news1);list.add(news2);list.add(news3);list.add(news4);list.add(news5);list.add(news6);//在列表的首部添加数据((LinkedList)list).addFirst(new News("", "新闻标题"));//删除并返回列表中的最后一个元素((LinkedList) list).removeLast();//循环输出集合中的全部数据for (int i = 0; i < list.size(); i++) {News n = (News)list.get(i);System.out.println(n.getTime());System.out.println(n.getTitle());}}}
