Programming Forums - Java socket Server compile errors..

I'm trying to make a socket server froma tutorial I found on the net. here is the code:

import java.io.*;

import java.net.*;



public class echo3 {

    public static void main(String args[]) {



// declaration section:

// declare a server socket and a client socket for the server

// declare an input and an output stream



        ServerSocket echoServer = null;

        String line;

        DataInputStream is;

        PrintStream os;

        Socket clientSocket = null;



// Try to open a server socket on port 9999

// Note that we can't choose a port less than 1023 if we are not

// privileged users (root)



        try {

           echoServer = new ServerSocket(9999);

        }

        catch (IOException e) {

           System.out.println(e);

        }   



// Create a socket object from the ServerSocket to listen and accept 

// connections.

// Open input and output streams



try {

           clientSocket = echoServer.accept();

           is = new DataInputStream(clientSocket.getInputStream());

           os = new PrintStream(clientSocket.getOutputStream());



// As long as we receive data, echo that data back to the client.



           while (true) {

             line = is.readLine();

             os.println(line); 

           }

        }   

catch (IOException e) {

           System.out.println(e);

        }

    }

}

When i compile it: javac echo3.java
it gives me this error:

Note: echo3.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.

after i run with deprecation it says:

echo3.java:40: warning: readLine() in java.io.DataInputStream has been deprecate (line = is.readLine();)

Any idea on how I can fix this? (This is on a freebsd system incase that matters)
