用JAVA析取URL为空怎么办

Question

如题所述

Answer 1

String urlStr = "";
URL url = new URL(urlStr);
//到了这里就已经在访问url了
HttpConnection conn = (HttpConnection) url.openConnection();
//这里是打开输入流,下载这个url的网页源码.剩下的要怎么做你自己看着办
InputStream is = conn.getInputStream();追问

是不是在String urlStr = "";
URL url = new URL(urlStr);
的后面加上
HttpConnection conn = (HttpConnection) url.openConnection();然后找个浏览器打开url网站就行了的意思?
