新闻列表的分页查询java代码实现

package com.ibeifeng.test;
//创建新闻测试类
public class newTest {
private long id;
private String title;
private String content;
private String author;
 
public newTest() {
  super();
}
 
public newTest(long id, String title, String content, String author) {
  this.id = id;
  this.title = title;
  this.cOntent= content;
  this.author = author;
}
 
public long getId() {
  return id;
}
 
public void setId(long id) {
  this.id = id;
}
 
public String getTitle() {
  return title;
}
 
public void setTitle(String title) {
  this.title = title;
}
 
public String getContent() {
  return content;
}
 
public void setContent(String content) {
  this.cOntent= content;
}
 
public String getAuthor() {
  return author;
}
 
public void setAuthor(String author) {
  this.author = author;
}
 
@Override
public String toString() {
  return "newTest [id=" + id + ", title=" + title + ", cOntent=" + content
      + ", author=" + author + "]";
}
 
 
}
2.开始查询

<%@ page import="com.ibeifeng.test.newTest"%>
<%
  String path = request.getContextPath();
  String basePath = request.getScheme() + "://"
      + request.getServerName() + ":" + request.getServerPort()
      + path + "/";
%>
<%
  List list = new ArrayList(107);//设定新闻行数为107行
  for (int i = 1; i <= 107; i++) {//list中添加新闻
    newTest news = new newTest(0L + i, i + "里约奥运", "马龙获得金牌-世界乒坛第五位男子“大满贯”得主", "福音");
 
    list.add(news);
  }//end of for...添加107条数据到集合中
    //int pageIndex=10;
  int iTitleIndex = list.size();//获取集合下表标
  int iTitlePages = iTitleIndex / 10
      + (iTitleIndex % 10 == 0 &＃63; 0 : 1);//获取页数的总数
  int ipage = 4;//开始的页数
   
  String str = request.getParameter("page");
  if (str != null && !str.trim().equals("")) {
    int newPage = Integer.valueOf(str);
 
    if (newPage <1) {
      ipage = 1;
    } else if (newPage > iTitlePages) {
      ipage = iTitlePages;
    } else {
      ipage = newPage;
    }
  }
  //创建一个新的集合（大小每个页面显示的新闻总数） 将107条数据分别存储到其中 
  List listPage = new ArrayList(10);
  int ipa = 10;//获取循环体的循环次数//最后一页只有七条数据
  if (ipage == iTitlePages) { //当当前页数为最后一页时，剩余几行则循环体之执行剩余的行的数次，
    ipa = list.size() - (iTitlePages - 1) * 10;
  }
  for (int i = 0; i 


  
    <%
      for (int i = 0; i
