First Very Simple Socket Program

Question

Hello,
I am learning about Sockets and ServerSockets and how I can use the. I am trying to make the simplest server/client program possible just for my understanding before I go deper into it. I have written two programs. theserver.java and theclient.java the sere code looks like this....
import java.net.*;
import java.io.*;
import java.util.*;
public class theserver
  public static void main(String[] args)
  {   //  IOReader r = new IOReader();
        int prt = 3333;
        BufferedReader in;
         PrintWriter out;
        ServerSocket serverSocket;
        Socket clientSocket = null;
try{
serverSocket = new ServerSocket(prt);  // creates the socket looking on prt (3333)
System.out.println("The Server is now running...");
while(true)
    clientSocket = serverSocket.accept(); // accepts the connenction
    clientSocket.getKeepAlive(); // keeps the connection alive
    out = new PrintWriter(clientSocket.getOutputStream(),true);
    in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
     if(in.ready())
     System.out.println(in.readLine()); // print it
catch (IOException e) {
    System.out.println("Accept failed:"+prt);
}and the client looks like this
import java.net.*;
import java.io.*;
public class theclient
public static void main(String[] args)
    BufferedReader in;
    PrintWriter out;
    IOReader r = new IOReader();
    PrintWriter sender;
    Socket sock;
  try{
    sock = new Socket("linuxcomp",3333);  // creates a new connection with the server.
    sock.setKeepAlive(true); // keeps the connection alive
    System.out.println("Socket is connected"); // confirms socket is connected.
    System.out.println("Please enter a String");
     String bob = r.readS();
      out = new PrintWriter(sock.getOutputStream(),true);
    out.print(bob); // write bob to the server
  catch(IOException e)
       System.out.println("The socket is now disconnected..");
}If you notice in the code I use a class I made called IOReader. All that class is, is a buffered reader for my System.in. (just makes it easier for me)
Ok now for my question:
When I run this program I run the server first then the client. I type "hello" into my system.in but on my server side, it prints "null" I can't figure out what I am doing wrong, if I am not converting correctly, or if the message is not ever being sent. I tried putting a while(in.read()) { System.out.println("whatever") } it never reaches a point where in.ready() == true. Kinda of agrivating. Because I am very new to sockets, I wanna aks if there is somthing wrong with my code, or if I am going about this process completely wrong. Thank you to how ever helps me,

An example of Creating a Client Socket (Java socket programming tutorial)
try {
        InetAddress addr = InetAddress.getByName("hotdir.biz");
        int port = 80;
        // This constructor will block until the connection succeeds
        Socket socket = new Socket(addr, port);
    } catch (UnknownHostException e) {
    } catch (IOException e) {
    // Create a socket with a timeout
    try {
        InetAddress addr = InetAddress.getByName("hotdir.biz");
        int port = 80;
        SocketAddress sockaddr = new InetSocketAddress(addr, port);
        // Create an unbound socket
        Socket sock = new Socket();
        // This method will block no more than timeoutMs.
        // If the timeout occurs, SocketTimeoutException is thrown.
        int timeoutMs = 2000;   // 2 seconds
        sock.connect(sockaddr, timeoutMs);
    } catch (UnknownHostException e) {
    } catch (SocketTimeoutException e) {
    } catch (IOException e) {
