Server.java Program:

import java.net.*;
import java.io.*;

public class Server
{
public static void main(String[] args) throws IOException{
Socket client= null;
PrintWriter pout=null;
ServerSocket sock=null;

try{
sock= new ServerSocket(51 55);
// now listen for connections

while(true){
client= sock.accept();

// we have a connection
pout = new PrintWriter(cli ent.getOutputSt ream(), true);

// write the date to the socket
pout.println(ne w java.util.Date( ).toString());

pout.close();
client.close();
}
}
catch (IOException ioe) {
System.err.prin tln(ioe);
}
finally {
if (client !=null)
client.close();
if (sock !=null)
sock.close();
}
}
Client.java Program:

import java.net.*;
import java.io.*;

public class Client
{
public static void main(String[] args) throws IOException{
InputStream in = null;
BufferedReader bin = null;
Socket sock = null;

try {
// make connection to socket
sock = new Socket("127.0.0 .1",5155);

in = sock.getInputSt ream();
bin = new BufferedReader( new InputStreamRead er(in));

String line;
while ((line= bin.readLine()) !=null)
System.out.prin tln(line);
}
catch (IOException ioe) {
System.err.prin tln(ioe);
}

After many years of using LISP, I'm taking a class in Java and finding the two roughly comparable in some ways and very different in other ways. Each has a decent size library of useful utilities as a standard portable part of the core language, the LISP package, and the java.lang package, respectively.

Hello, I'm starting to learn about java networking. What I want to do is for now, just make a server that listens to connections through a port, and accepts it's connections from the client. I don't have that many connections about networking, so I don't know any good book that gives a nice comprehensive introduction to java networking.

No, I'm not a troll, just angry. I just started learning C++, and find it extremely lacking compared to Java. For example, I had to write my own functions to do something as simple as a case insensitive string comparison, and a substring search. Then I found that there are no networking classes to speak of (except sockets). After I thought about it, C++ really pales by comparison. Java has a rich set of networking classes, regular...
