int data;//从输入流中获取数据 
URL url=new URL("http://www.sohu.com"); 
//创建连接的地址 
HttpURLConnection connection=url.openConnection(); 
//打开连接 
int responsCode=connection. getResponseCode(); 
//返回Http的响应状态码 
InputStream input=connection.getInputStream(); 
//获取输入流 
System.out.println("responseCode:"+responseCode); 
While((data=input.read())!=-1) 
System.out.println(data); 
//将获取的数据打到屏幕显示出来
