I have created a server and a client program as follows:
/*********Beginning of testServer.java*********/
class testServer {
public static void main ( String arg[] ) {
ServerSocket s = (ServerSocket) null;
Socket lsock;
OutputStream out;
InputStream in;
int port = 1112;
try s = new ServerSocket(port, 300);
catch (IOException e) {
System.out.println("\nServer time out!");
System.exit(-1);
}
while (true) {
try {
lsock = s.accept();
in = lsock.getInputStream();
System.out.println((int)in.read());
out = lsock.getOutputStream();
out.write(2);
lsock.close();
} catch (IOException e) {}
}
}
}
/**********End of testServer*********/
/********Beginning of testClient.java******/
import java.net.*;
import java.io.*;
class testClient {
public static void main (String arg[]) {
Socket lsock;;
int lport = 1112;
try {
lsock = new Socket (arg[0],lport);
send(lsock,1);
while (lsock.getInputStream() != null)
receive(lsock);
lsock.close();
} catch (IOException e) {}
}
public static void send (Socket s, int out) throws IOException {
OutputStream sout;
sout = s.getOutputStream();
sout.write(out);
}
public static void receive (Socket s) throws IOException {
InputStream in;
in = s.getInputStream();
System.out.println((int)in.read());
}
}
/********** End of testClient*****/
Questions: I like the two programs to interact with one another. For
instance, I want both the server and client to know if there
is an incoming signal. If there is an incoming message for
the server, I want it to print on the screen. I want the server
and the client to send messages randomly. Hence, if the client
is sending a message at a particular time, the server need to
know there is a message and get the message from the socket.
I hope I am clear enough in my question and please help me on that. Thanks.
