聊天室/服务器/客户端/线程

服务器端

public class ChatRoomServer {

// 聊天室中的成员

static List<Socket> socketList = new ArrayList<>();

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

ServerSocket serverSocket = new ServerSocket(9999);

Socket socket = serverSocket.accept(); // 等待客户端连接

socketList.add(socket); // 将新连接的socket存入集合

System.out.println(socket.getInetAddress() + "上线了...");

System.out.println(socketList);

}

// 读取&展示消息的线程

static class ReadMsgThread implements Runnable {

private Socket socket ;

public ReadMsgThread(Socket socket) {

this.socket = socket;

}

@Override

public void run() {

try {

boolean flag = true;

while (true) {

// 接收成员发送的消息

//获取输入流 读取消息

InputStream in = socket.getInputStream();

byte[] bytes = new byte[1024];

int read = in.read(bytes);

// 张三&你好

String msg = new String(bytes , 0 ,read);

// 解析

String[] split = msg.split("&");

String nickName = split[0]; // 昵称

String content = split[1]; // 要发送的内容

if (flag){

System.out.println(nickName + "上线了...");

flag = false;

}

System.out.println(nickName + "说：" + content);

}

} catch (Exception e) {

// e.printStackTrace();

}

}

}

客户端

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

Socket socket = new Socket("localhost", 9999);

// 启动接收 服务端 群发消息的线程

new Thread( new ReadServerMsg(socket)).start();

Scanner sc = new Scanner(System.in);

System.out.println("请设置您的昵称：");

String nickName = sc.next() ;

while (true){

OutputStream out = socket.getOutputStream();

System.out.println("请输入您要发送的内容:");

String content = sc.next();

// 打包信息 昵称 与 内容 使用 & 连接

// 张三&你好

String msg = nickName + "&" + content ;

out.write(msg.getBytes());

}

}

static class ReadServerMsg implements Runnable{

private Socket socket ;

public ReadServerMsg(Socket socket) {

this.socket = socket;

}

@Override

public void run() {

try{

while (true){

InputStream in = socket.getInputStream();

byte[] bytes = new byte[1024];

int read = in.read(bytes);

String msg = new String(bytes , 0 , read);

System.out.println("server:" + msg);

}

}catch (Exception e ){

}

}

}

}
