Question

我正在尝试用java测试一些东西，但我有以下错误：

第16行：令牌“;”上的语法错误，{此标记后的预期

在第36行：语法错误，插入“}”以完成ClassBody

我已经在第36行插入了一个括号，但原则上没有必要......第16行的错误仍然存在

有人可以帮我发现问题是什么？

非常感谢你。

以下是我正在使用的类NewsCrawler.java的代码：

package upf.dad.proyecto;

import java.net.URL;
import java.util.Iterator;

import org.jsoup.Jsoup;

import com.sun.syndication.feed.synd.SyndEntry;
import com.sun.syndication.feed.synd.SyndFeed;
import com.sun.syndication.io.SyndFeedInput;
import com.sun.syndication.io.XmlReader;

public class NewsCrawler {

        URL url = new URL("https://news.google.com/news/section?topic=t&ned=es&output=rss"); 
        XmlReader reader = null;


    try {   
        reader = new XmlReader(url);    
        SyndFeed feed = new SyndFeedInput().build(reader);

        for (Iterator i = feed.getEntries().iterator(); i.hasNext();) {
                SyndEntry entry = (SyndEntry) i.next();
                System.out.println("Title: " + entry.getTitle());
                System.out.println("   Description: " + Jsoup.parse(entry.getDescription().getValue()).text());
                System.out.println("   Date: " + entry.getPublishedDate());       
                System.out.println("   Link: " + entry.getLink());    
        }
    } finally {
        if (reader != null) {       
            reader.close();    
        } 
    }

}

public class NewsCrawler
