如何通过java套接字接收字节

ServerSocket serverSocket = new ServerSocket(port);

Socket socket = serverSocket.accept();

InputStream inputStream = socket.getInputStream();

byte[] buffer = new byte[1024];

int bytesRead = inputStream.read(buffer);

String receivedData = new String(buffer, 0, bytesRead);

import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class SocketServer {
    public static void main(String[] args) {
        int port = 8080;
        try {
            ServerSocket serverSocket = new ServerSocket(port);
            System.out.println("Server listening on port " + port);

            Socket socket = serverSocket.accept();
            System.out.println("Client connected: " + socket.getInetAddress());

            InputStream inputStream = socket.getInputStream();
            byte[] buffer = new byte[1024];
            int bytesRead = inputStream.read(buffer);

            String receivedData = new String(buffer, 0, bytesRead);
            System.out.println("Received data: " + receivedData);

            socket.close();
            serverSocket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
