代码如下：
public class test {
public static void main(String[] args) throws Exception {
URL url = new URL("https://play.google.com/……e");
URLConnection connection = url.openConnection();
connection.connect();
InputStream inputstr = connection.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(inputstr,"utf-8"));
String s = null;
int temp = 0;
while( ( s = br.readLine()) != null){
System.out.println(s);
}
}
}
报错如下：

前几天还能跑的程序，最近突然就不能跑了，而且除了谷歌的这个网页，其他的网页都能抓，求大神帮助啊！谢谢！！

你这是https的链接，没见你指定端口，而且https是需要证书的，你这样写应该是不行的
试试apache的httpclient那个库吧
