how can I listen to a certain port using Java?

Sorry I'm asking this, but I'm new to socket programming in general. I'd like to read all the data that comes from a certain port, say 8080. how can I do it? can you give me a simple example, on which I can build a solid understanding?

Thank you!

This listens from a port, gets the socket, creates a reader from the stream and prints every line that comes from the socket:

ServerSocket serverSocket = new ServerSocket(8080);

Socket socket = serverSocket.accept();
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));

String line = null;
while((line = br.readLine()) != null){
    System.out.println("Line from socket: "+line);
}

From there I'm sure you can go on by yourself
