我想问一个关于Java的问题。我已经使用Java中的URLConnection来检索DataInputStream。我想将DataInputStream转换为Java中的String变量。我该怎么办？谁能帮我。谢谢。

以下是我的代码：

URL data = new URL("http://google.com");
URLConnection dataConnection = data.openConnection();
DataInputStream dis = new DataInputStream(dataConnection.getInputStream());
String data_string;
// convent the DataInputStream to the String

回答：

import java.net.*;
import java.io.*;
class ConnectionTest {
    public static void main(String[] args) {
        try {
            URL google = new URL("http://www.google.com/");
            URLConnection googleConnection = google.openConnection();
            DataInputStream dis = new DataInputStream(googleConnection.getInputStream());
            StringBuffer inputLine = new StringBuffer();
            String tmp; 
            while ((tmp = dis.readLine()) != null) {
                inputLine.append(tmp);
                System.out.println(tmp);
            }
            //use inputLine.toString(); here it would have whole source
            dis.close();
        } catch (MalformedURLException me) {
            System.out.println("MalformedURLException: " + me);
        } catch (IOException ioe) {
            System.out.println("IOException: " + ioe);
        }
    }
}
