1.1 Changes: ConnectionTest Example

The ConnectionTest example uses the DataInputStream.readLine method which has been deprecated in the JDK 1.1 because it does not convert correctly between bytes and characters. Most programs that use DataInputStream.readLine can make a simple change to use the same method from the new BufferedReader class instead. Simply replace code of the form:

DataInputStream d = new DataInputStream(in);

with:

BufferedReader d = new BufferedReader(new InputStreamReader(in));

ConnectionTest is one of those programs which can make this simple change. Here is the new version of ConnectionTest:

import java.net.*;
import java.io.*;

class ConnectionTest {
    public static void main(String[] args) {
        try {
            URL yahoo = new URL("http://www.yahoo.com/");
            URLConnection yahooConnection = yahoo.openConnection();
            BufferedReader br = new BufferedReader(
			new InputStreamReader(yahooConnection.getInputStream()));
            String inputLine;

            while ((inputLine = br.readLine()) != null) {
                System.out.println(inputLine);
            }
            br.close();
        } catch (MalformedURLException me) {
            System.out.println("MalformedURLException: " + me);
        } catch (IOException ioe) {
            System.out.println("IOException: " + ioe);
        }
    }
}
