import java.net.ServerSocket;
import java.net.Socket;
public class SocketServer {
private static final int PORT = 8088;
public static void main(String[] args) {

try {
server = new ServerSocket(PORT);
while (true) {
Socket client = server.accept();
new Thread(new Server(client)).start();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
class Server implements Runnable {
private Socket client;
public Server(Socket client) {
this.client = client;
}
public void run() {
DataOutputStream output = null;
try {
output = new DataOutputStream(client.getOutputStream());
output.writeUTF("你好我是服务器");
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (output != null) output.close();

} catch (IOException e) {}
}
}

2、客户端
import java.io.DataInputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
public class Client extends Socket {
private static final int PORT = 8088;
public static void main(String[] args) {
Socket socket = null;
try {
socket = new Socket("127.0.0.1", PORT);
DataInputStream in = new DataInputStream(socket.getInputStream());
String res = in.readUTF();
System.out.println(res);
if (in != null) in.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (socket != null) {
try {
socket.close();
} catch (IOException e) {}
