Creating java server problem

[NitinSawant]

Hello friends, actually i have a problem with following programs:
First:---------
import java.net.*;
import java.io.*;
public class SimpleServer{
public static void main(String[] a){
ServerSocket s=null;
try{
s=new ServerSocket(5432);
}catch(IOException e){
e.printStackTrace();
}
while(true){
try{
Socket s1=s.accept();
OutputStream s1out=s1.getOutputStream();
BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(s1out));
bw.write("Hello Net World!!");
bw.close();
s1.close();
}catch(IOException e){
e.printStackTrace();
}
}
}
}

Second:----------
import java.net.*;
import java.io.*;

public class SimpleClient {
public static void main(String[] a) {
try
{
Socket s1 = new Socket("127.0.0.1", 5432);
InputStream is = s1.getInputStream();
DataInputStream dis = new DataInputStream(is);
System.out.println(dis.readUTF());
br.close();
s1.close();
}
catch (ConnectException con)
{
System.err.println("Coult not connect");
}
catch (IOException ex)
{
//ex.printStackTrace();
}
}
}

when i compile and run these programs in two different cmd windows nothing is shown as output, pls help!!

Better use a (Buffered)Reader on the client side because the server side uses
a BufferedWriter for the printing purposes. A DataInputStream is normally used
for reading binary data.

kind regards,

thanx bro, can you pls tell me how to use that reader???

Simply read the API documentation. A BufferedReader even has a readLine()
method. If you use a PrintWriter on the server side all will be fine.

Similar to how you have done the writing with the BufferedWriter above. This time you'll be reading so use BufferedReader.

P.S Use code tags when posting code
P.P.S Nice avatar

thanx a lot r035198x, JosAH
I've modified it and it is working fine ..

import java.net.*;
import java.io.*;
 
public class SimpleClient {
    public static void main(String[] a) {
        try
        {
            Socket s1 = new Socket("127.0.0.1", 5432);
            InputStream is = s1.getInputStream();
            BufferedReader rdr=new BufferedReader(new InputStreamReader(is));
            String str=rdr.readLine();
            System.out.println(str);
            rdr.close();
            s1.close();
        }
        catch (ConnectException con)
        {
            System.err.println("Coult not connect");
        }
        catch (IOException ex)
        {
            //ex.printStackTrace();
        }
    }
