import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.*;  public class loadurl {  public static void main(String args[]) {   String a = null;   try {    String url = "（这里替换成任意网页的网址）";    BufferedReader in = new BufferedReader(new InputStreamReader(      new URL(url).openConnection().getInputStream(), "GB2312"));//GB2312可以根据需要替换成要读取网页的编码    while ((a = in.readLine()) != null) {     System.out.println(a);    }   } catch (MalformedURLException e) {   } catch (IOException e) {   }  } } 

BufferedReader in = new BufferedReader(new InputStreamReader(...))

(new URL(url).openConnection().getInputStream(), "GB2312")
