帮我写一段Java爬虫代码

答：以下是一段简单的Java爬虫代码：import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class JavaCrawler {

public static void main(String[] args) throws IOException {
// 要爬取的网页链接
String url = "https://www.example.com/";
// 创建一个URL对象
URL u = new URL(url);
// 打开URL对应的资源输入流
BufferedReader in = new BufferedReader(new InputStreamReader(u.openStream()));
// 遍历抓取到的每一行内容
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
// 关闭输入流
in.close();
}
}
