Chatting Menggunakan Gambar Pada Java

Chatting menggunakan java sudah dibahas sebelumnya, sekarang bagaimana menjalankan chatting java dengan menampilkan gambar. Ada 2 program yang harus dibuat, yaitu program chat server dan program chat client. Untuk program chat server, listing programnya adalah:
import java.io.*;
import java.net.*;
import java.util.*;

public class ChatServer {

    private static int uniqueId;
    private ArrayList<ChatServer.ClientThread> clients;
    private int port;
    private boolean keepGoing;

    public ChatServer() {
        this.port = 9999;

Pastikan semua komputer terhubung dengan internet, Jalankan program chat server, biarkan sampai chat client teman terhubung:

Kemudian jalankan program chat client pada komputer teman, pada kolom server: masukkan IP pada komputer server, port: “9999” dan Username dengan nama kita sendiri “Mega” kemudian tekan tombol “Masuk”:

Tunggu sampai koputer teman yang lain terhubung, setelah terhubung, anda sudah dapat menjalankan chatting bersama-sama:
