The program below is compiled started with java QuoteServermain. When a client
attempts to connect to it using "localhost" as the host name. We are refused
the connection. When the real host name is used the connection is granted.
import java.net.*;
import java.io.*;
//
// Open a Socket on the server and send a price for the given stock
// read is done on this socket. Use localhost and port 7000
//
class QuoteServerMain {
public static void main(String args[]) {
byte b[] = new byte [100];
String response;
int slength;
Double price;
ServerSocket s;
Socket s1;
int nbytes;
int PortNumber = 7000;
InputStream inputStream;
OutputStream outputStream;
try {
s = new ServerSocket(PortNumber,20000);
} catch(Exception e) {
System.out.println("Unable to create socket " + PortNumber);
return;
}
// Look for requests for data constantly
while ( true ) {
try {
s1 = s.accept();
inputStream = s1.getInputStream();
outputStream = s1.getOutputStream();
nbytes = inputStream.read(b,0,10); // Read the input

String one = new String(price.toString()); // Make up a price
slength = one.length();
one.getBytes(0,slength,b,0);
outputStream.write(b,0,slength);

} catch(Exception e) {
