Java 如何从接收到的 UDP 字节中解析 double 值？

Question

int port = 18000;
DatagramSocket serverSocket = new DatagramSocket(port);
byte[] receiveData = new byte[8];

System.out.println("Server Listing on Port: "+port);
String x;

while (true){
  DatagramPacket receivePacket = new DatagramPacket(receiveData, receiveData.length);
  serverSocket.receive(receivePacket);

?? Double x = new Doulbe.parseBytes(recievedPacket)

Answer 1

你可以使用 ByteBuffer

Double x = ByteBuffer.wrap(receiveData).getDouble();
