Finding alternative to deprecation

Question

hi, i'm learning java sockets programming and i stumble upon these codes...
import java.net.*;
import java.io.*;
public class TestClient2{
     boolean connStat=false;
     Socket sock=null;
     DataInputStream streamIn=null;
     DataOutputStream streamOut=null;
     public TestClient2(){
          try{
               sock=new Socket("127.0.0.1",1024);
               System.out.println("Connected to server");
               streamIn=new DataInputStream(System.in);
               streamOut=new DataOutputStream(sock.getOutputStream());
               while(!connStat){
                    try{
                         String line=streamIn.readLine(); //THE OFFENDING DEPRECATED STATEMENT
                         streamOut.writeUTF(line);
                         streamOut.flush();
                         connStat=line.equalsIgnoreCase("bye");
                    catch(Exception err){
                         System.out.println(err);
                         connStat=true;
               if(streamOut!=null)     streamOut.close();
               if(streamIn!=null)     streamIn.close();
               if(sock!=null)          sock.close();
          catch(Exception err){
               System.out.println(err);
     public static void main(String[]args){
          TestClient2 tc2=new TestClient2();
}as u can see, the statement with caps comments is the cause of the deprecation during compilation
i tried to use readUTF, but as a result, the program will just hang
do u guys know of a better alternative to that statement?
thx,

See the API docs whenever you have a deprecation warning.
http://java.sun.com/j2se/1.4.2/docs/api/java/io/DataInputStream.html#readLine()
It says to use BufferedReader.readLine().
