Socket stuff... Connection works but neither client nor server will receive

Question

Okay, here's the deal...
I have a serversocket and a clientsocket in the same program. I have the client connect to 127.0.0.1 and the server accepts a connection. Both server and client make a thread to listen to one another. Then the server sends something to the client. The client doesn't catch anything. When I use the client to send to the server, the server also doesn't catch anything. Also, when I add the line "System.out.println(fromServer.readln())" after the connecting instead of in a separate thread, it gets totally weird and starts jumping back and forth between lines within the same try block. The line order gets random and some get executed twice. I'm using the IntelliJ software to program / debug. The application always gets stuck at the line I mentioned before. . I have no idea what the hell is going on. Can any one please please help me? =(
P.S. I could add the code but I'm not sure what to add and if I added all of it it'd kind of be a lot so... if you need to take a look at it tell me what parts you want or if you want the full thing or whatever. I don't see a way to attach files to posts =p otherwise I could have attached the project.

try this:
Client:
import java.io.*;
import java.net.*;
public class client
     Socket soc;
     DataInputStream in;
     PrintStream out;
     public client()
          String str="";
          try
               soc = new Socket("127.0.0.1",5432);
               in = new DataInputStream(soc.getInputStream());
               out = new PrintStream(soc.getOutputStream());
               while((str=in.readLine())!=null)
                    System.out.println(str);
               in.close();
               out.close();
          catch(Exception e)
               System.out.println(e);
     public static void main(String args[])
          client obj = new client();
}Server:
import java.io.*;
import java.net.*;
public class server
     ServerSocket ss;
     Socket soc;
     DataInputStream in;
     PrintStream out;
     public server()
          String str="";
          try
               ss = new ServerSocket(5432);
               while(true)
                    soc = ss.accept();
                    in = new DataInputStream(soc.getInputStream());
                    out = new PrintStream(soc.getOutputStream());
                    out.println("Connected !!");
          catch(Exception e)
               System.out.println(e);
     public static void main(String args[])
          server obj = new server();
}
