java - 在java中使用ipv6进行客户端/服务器套接字编程

Question

我正在尝试通过 wifi direct 连接两个设备，然后通过套接字在它们之间传输数据。

在服务端我有这个代码

  ArrayList<SendReceive> threadList = new ArrayList<>();
public class ServerClass extends Thread{
    
      ServerSocket server;
      {
          try {
              server = new ServerSocket(8888, 5);

          } catch (IOException e) {
              e.printStackTrace();
          }
      }
      public void run() {
          while (true) {
              try {
                  Socket client =server.accept();
                  runOnUiThread(new Runnable() {
                      @Override
                      public void run() {
                          appendStatus("Connection from " + client.getRemoteSocketAddress());
                      }
                  });
                  SendReceive serverThread=new SendReceive(client);
                  threadList.add(serverThread);
                  serverThread.start();
              } catch (Exception e) {
                  System.out.println("Error occured in main: " + e.getStackTrace());
              }
          }
      }
     
  }

在客户端我有这个代码

 public class ClientClass extends Thread{
        Socket socket;
        String hostAdd;
        public ClientClass(InetAddress hostAddress){
            hostAdd=hostAddress.getHostAddress();

            socket=new Socket();
        }

        @Override
        public void run() {
            try {
                socket.connect(new InetSocketAddress(hostAdd,8888),500);
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        CONSt.setText("now the client connected to server.");
                    }
                });
                sendReceive=new SendReceive(socket);
                sendReceive.start();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

注意：SendReceive 的代码是

private class SendReceive extends Thread{
        private Socket socket;
        private InputStream inputStream;
        private OutputStream outputStream;
        public SendReceive(Socket skt){
            socket=skt;
            try {
                inputStream=socket.getInputStream();
                outputStream=socket.getOutputStream();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void run() {
            byte[] buffer =new byte[1024];
            int bytes;
            while (socket!=null){
                try {
                    bytes=inputStream.read(buffer);
                    if(bytes>0){
                        String tempMsg=new String(buffer,0,bytes);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                appendStatus(tempMsg);
                            }
                        });
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        public void write(byte[] bytes){
            try {
                outputStream.write(bytes);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

这项工作与 ipv4 地址类似

ClientClass clientClass= new ClientClass( InetAddress.getByName("192.168.49.1"));
  clientClass.start();

但不适用于 ipv6 地址

 ClientClass clientClass= new ClientClass( InetAddress.getByName("fe80::58a2:b5ff:fe7f:ea51%p2p0"));
  clientClass.start();

我需要使用 ipv6 ，有什么问题！！为什么这段代码不能与 ipv6 和 ipv4 一起工作，我如何使它与 ipv6 一起工作。

我将不胜感激任何答案
