我想把下面这个程序中的两个System.out.println()括号输出数据存到本地文档中以便打印，该怎么弄呢？求完整的代码
package appgamerank;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileWriter;
import java.io.IOException;
import java.net.MalformedURLException;

public class AppGameRank {
/**

public static void main(String[] args) {
// TODO code application logic here
AppGameRank rh = new AppGameRank();
rh.saveHtml();
rh.getMsgfromHtml();
}
public void saveHtml(){
HttpClient client = new HttpClient();
String htmlurl = "http://www.appannie.com/top/iphone/united-states/games/";
System.out.println(htmlurl);
HttpMethod method = new GetMethod(htmlurl);

client.executeMethod(method);
System.out.println(method.getStatusLine());
String html = method.getResponseBodyAsString();
FileWriter fw = new FileWriter("D:\\Top Charts - iPhone - United States - Games App Annie.htm" );
fw.write(html);
fw.close();
} catch (HttpException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void getMsgfromHtml(){
try
{
//URL url = new URL("http://www.appannie.com/top/iphone/united-states/games/");
//Document doc = Jsoup.parse(url, 3000000);
File f = new File("D:\\Top Charts - iPhone - United States - Games App Annie.htm");
Document doc = Jsoup.parse(f,"UTF-8");
Elements tables = doc.select("table");
Element table = tables.get(1);
Elements trs =table.getElementsByTag("tr");
for(Element tr: trs)
{
Elements tds = tr.children();
Element td = tds.get(2);//表示 Free那一列
Elements span =td.getElementsByTag("span");
String content = span.get(0).html();
if(content.contains("\u25b2"))
{
String up = content.replace("\u25b2", "");//正三角，倒三角是\u25bc
int upnum = Integer.parseInt(up);
if(upnum >=30)
{
Elements a = td.getElementsByTag("a");
System.out.println(a.get(0).html());
}
}
else if(content.contains("(new)"))
{
String up = content.replace("(new)","");
Elements a = td.getElementsByTag("a");
System.out.println(a.get(0).html());
}
}
} catch (MalformedURLException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
}
}
[解决办法]
getMsgfromHtml方法少复制了。。。这个才是完整的
public void getMsgfromHtml() throws MalformedURLException, IOException { PrintWriter out = null; try { out = new PrintWriter("D:/test.log"); // URL url = new // URL("http://www.appannie.com/top/iphone/united-states/games/"); // Document doc = Jsoup.parse(url, 3000000); File f = new File( "D:\\Top Charts - iPhone - United States - Games App Annie.htm"); Document doc = Jsoup.parse(f, "UTF-8"); Elements tables = doc.select("table"); Element table = tables.get(1); Elements trs = table.getElementsByTag("tr"); for (Element tr : trs) { Elements tds = tr.children(); Element td = tds.get(2);// 表示 Free那一列 Elements span = td.getElementsByTag("span"); String content = span.get(0).html(); if (content.contains("\u25b2")) { String up = content.replace("\u25b2", "");// 正三角，倒三角是\u25bc int upnum = Integer.parseInt(up); if (upnum >= 30) { Elements a = td.getElementsByTag("a"); // System.out.println(a.get(0).html()); println(out, a.get(0).html()); } } else if (content.contains("(new)")) { String up = content.replace("(new)", ""); Elements a = td.getElementsByTag("a"); // System.out.println(a.get(0).html()); println(out, a.get(0).html()); } } } finally { if (out != null) { out.close(); out = null; } } }
