import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.nio.ByteBuffer;
import java.nio.ByteOrder;
import java.util.BitSet;
public class Main {
public static void main(String args) {
// You can use print statements as follows for debugging, they’ll be visible
// when running tests.
System.out.println(“Logs from your program will appear here!”);
// Uncomment this block to pass the first stage
try (DatagramSocket serverSocket = new DatagramSocket(2053)) {
while (true) {
final byte buf = new byte[512];
final DatagramPacket packet = new DatagramPacket(buf, buf.length);
serverSocket.receive(packet);
System.out.println(“Received data”);
final byte bufResponse = new byte[512];
// final byte bufResponse = new byte[512];
short ID = (short)1234;
final var bitset = new BitSet(8);
bitset.flip(7);
final var bufResponse = ByteBuffer.allocate(512)
.order(ByteOrder.BIG_ENDIAN)
.putShort(ID)
.put(bitset.toByteArray())
.put((byte)0)
.putShort((short)0)
.putShort((short)0)
.putShort((short)0)
.putShort((short)0)
.array();
final DatagramPacket packetResponse = new DatagramPacket(
bufResponse, bufResponse.length, packet.getSocketAddress());
serverSocket.send(packetResponse);
}
} catch (IOException e) {
System.out.println("IOException: " + e.getMessage());
}
}
}

to be honest i dont know can you help me out??
