Pada bagian kali
ini, Program yang dibuat, guna untuk mengetahui info server dan info client suatu
komputer. Berikut adalah listing codenya dan eksekusi dari program yang telah
dibuat.
A) infoserver.java
import
java.io.*;
import
java.net.*;
import
java.util.*;
public
class infoserver {
private
final int INFO_PORT=50000;
private
String datafromClient;
public
infoserver() {
BufferedReader
inFromClient;
DataOutputStream
outToClient;
Socket
serverSocket;
try {
ServerSocket
infoserver =
new
ServerSocket(INFO_PORT);
System.out.println("Server
siap...");
while
(true){
serverSocket
= infoserver.accept();
System.out.println("Ada
client" +
"yang
terkoneksi!");
inFromClient
=
new
BufferedReader(
new
InputStreamReader(
serverSocket.getInputStream()));
outToClient
=
new
DataOutputStream(
serverSocket.getOutputStream());
outToClient.writeBytes("InfoServer
versi 0.1\n"+
"hanya
untuk testing..\n"+
"Silahkan
berikan perintah TIME|NET|QUIT\n");
boolean
isQUIT = false;
while
(!isQUIT) {
datafromClient
= inFromClient.readLine();
if
(datafromClient.startsWith("TIME")){
outToClient.writeBytes(new
Date().toString()
+ "\n");
} else if
(datafromClient.startsWith("NET")){
outToClient.writeBytes(
InetAddress.getByName("localhost").toString()+
"\n");
} else if
(datafromClient.startsWith("QUIT"))
{
isQUIT =
true;
}
}
outToClient.close();
inFromClient.close();
serverSocket.close();
System.out.println("Koneksi
client sudah tertutup..");
}
}
catch
(IOException ioe) {
System.out.print("error:"
+ ioe);
}
catch
(Exception e) {
System.out.print("error:"
+ e);
}
}
public
static void main(String[]args) {
new
infoserver();
}
}
Jalankan program
yang telah dibuat. Dengan cara klik ctrl+1 lalu ctrl+2, maka tampilan server
akan seperti berikut:
B)
InfoClient.java
import
java.net.*;
import
java.io.*;
import
java.util.*;
public
class InfoClient {
private
final int INFO_PORT=50000;
private
final String TargetHost = "localhost";
private
final String QUIT = "QUIT";
public
InfoClient() {
try {
BufferedReader
inFromUser =
new
BufferedReader(new
InputStreamReader(System.in));
Socket
clientSocket = new
Socket(TargetHost,
INFO_PORT);
DataOutputStream
outToServer =
new
DataOutputStream(
clientSocket.getOutputStream());
BufferedReader
inFromServer =
new
BufferedReader(
new
InputStreamReader(
clientSocket.getInputStream()));
System.out.println(inFromServer.readLine());
System.out.println(inFromServer.readLine());
System.out.println(inFromServer.readLine());
System.out.println("");
boolean
isQuit = false;
while
(!isQuit) {
System.out.print("Ketikkan
Perintah Anda : ");
String cmd
= inFromUser.readLine();
cmd =
cmd.toUpperCase();
if
(cmd.equals(QUIT)) {
isQuit =
true;
}
outToServer.writeBytes(cmd
+ "\n");
String
result = inFromServer.readLine();
System.out.println("Dari
Server: " + result);
}
outToServer.close();
inFromServer.close();
clientSocket.close();
}
catch
(IOException ioe) {
System.out.println("Error:"
+ ioe);
}
catch
(Exception e) {
System.out.println("Error:"
+ e);
}
}
public
static void main(String[]args) {
new
InfoClient();
}
}
