Client Server Menggunakan Java Programming Afriduarchan3:12 PM 1 komentar

Pada praktikum Labti ini saya menggunakan java programming dalam penggunaan client dan server. dan dijalankan menggunakan aplikasi Neatbens.berikut adalah code yang digunakan.

Main.java (Clientapp)

package clientapp;

import java.io.*;

import java.net.*;

public class Main {

    public static void main(String[] args) throws IOException {

        Socket client = null;       

        InputStream in = null;

        OutputStream out = null;

        byte[] receiveMsg =  new byte[64];

        try {

            client = new Socket("Afriduarchan-PC", 8080);

            in = client.getInputStream();

            out = client.getOutputStream();

        } catch (UnknownHostException e) {

            System.err.println(e.getMessage());

            System.exit(1);

        } catch (IOException e) {

            System.err.println(e.getMessage());

            System.exit(1);

        }

        String fromServer;

        String fromUser;

        in.read(receiveMsg);

        fromServer = new String(receiveMsg);

        System.out.println("Server: " + fromServer);

        fromUser = "Salam dari client";

        System.out.println("Kirim ke server: " + fromUser);

        out.write(fromUser.getBytes());

        fromUser = "Ini data dari client";

        System.out.println("Kirim ke server: " + fromUser);

        out.write(fromUser.getBytes());

        fromUser = "Keluar";

        out.write(fromUser.getBytes());

        System.out.println("Kirim ke server: " + fromUser);           

        out.close();

        in.close();

        client.close();}}

Main.java(Serverapp)

package serverapp;

import java.io.*;

import java.net.*;

public class Main {

    public static void main(String[] args) throws IOException {

        ServerSocket server = null;

        Socket client = null;

        byte[] receiveBuf = new byte[64];

        int recvMsgSize;       

        try {

            server = new ServerSocket(8080);

            System.out.println("Server started");

            client = server.accept();

            System.out.println("Client connected");           

        } catch (IOException e){

          System.out.println(e.getMessage());

          System.exit(-1); }

        InputStream in = client.getInputStream();

        OutputStream out = client.getOutputStream();

        String data;

        data = "Salam dari server";

        out.write(data.getBytes());

        java.util.Arrays.fill(receiveBuf, (byte)0);

        while (true) {

            recvMsgSize = in.read(receiveBuf);

            data = new String(receiveBuf);

            if (data.trim().equals("Keluar")){

                out.write(data.getBytes());

                break;

            }

            java.util.Arrays.fill(receiveBuf, (byte)0);

            System.out.println("Client: " + data);

        }

        out.close();

        in.close();

        client.close();

        server.close();}}

dan hasil dari output program diatas adalah sebagai berikut:

- ini adalah output dari server 

-ini adalah output dari client

demikian sedikit berbagi ilmu mengenai pemrograman jaringan.semoga bermanfaat. GBU
