在服務器上以十六進制接收數據？

Question

我正在向服務器發送字符串，並且在服務器端通過緩衝區迭代時獲取ASCCII字符。我如何發送字符串在服務器上以十六進制形式接收它？

代碼

String message; 
String result; 
String aString = "#2016011400000060.00#010104#004500##"; 
// String aString = "###"; 
BufferedReader inFromUser = new BufferedReader(new StringReader(aString)); 

Socket clientSocket = new Socket("localhost", 1000); 
DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream()); 
BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); 
message = inFromUser.readLine(); 
outToServer.writeBytes(message + '\n'); 
result = inFromServer.readLine(); 
System.out.println(result); 
clientSocket.close();
