Membuat Info Client

Pertama, Siapkan aplikasi untuk menuliskan perintah coding.
Jika menggunakan Sistem Operasi Windows, anda bisa menggunakan Textpad / Notepad kemudian akan di Compile/ Execute dengan Java.
Jika menggunakan Linux, anda bisa menggunakan Geany / Notepadqq kemuadian akan di Compile /Execute dengan Java.

Lalu Tulis Perintah Coding seperti ini:

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("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();
}
}

Lalu Hasil Outputnya akan seperti ini :
