如何在java nio中创建多个监听同一端口的udp客户端？

import java.io.IOException;
import java.net.InetSocketAddress;
import java.nio.ByteBuffer;
import java.nio.channels.DatagramChannel;
import java.nio.channels.SelectionKey;
import java.nio.channels.Selector;
import java.util.Iterator;

public class MultipleUdpClients {
    private static final int PORT = 8888;
    private static final int BUFFER_SIZE = 1024;

    public static void main(String[] args) {
        try {
            Selector selector = Selector.open();

            // 创建多个DatagramChannel对象
            DatagramChannel channel1 = DatagramChannel.open();
            DatagramChannel channel2 = DatagramChannel.open();

            // 将每个DatagramChannel对象注册到Selector上
            channel1.configureBlocking(false);
            channel1.register(selector, SelectionKey.OP_READ);
            channel1.bind(new InetSocketAddress(PORT));

            channel2.configureBlocking(false);
            channel2.register(selector, SelectionKey.OP_READ);
            channel2.bind(new InetSocketAddress(PORT));

            ByteBuffer buffer = ByteBuffer.allocate(BUFFER_SIZE);

            while (true) {
                selector.select();

                Iterator<SelectionKey> keyIterator = selector.selectedKeys().iterator();
                while (keyIterator.hasNext()) {
                    SelectionKey key = keyIterator.next();
                    keyIterator.remove();

                    if (key.isReadable()) {
                        DatagramChannel channel = (DatagramChannel) key.channel();
                        buffer.clear();
                        channel.receive(buffer);
                        buffer.flip();

                        // 处理接收到的数据包
                        // ...

                        System.out.println("Received data from " + channel.getRemoteAddress() + ": " + new String(buffer.array()));
                    }
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
