    Default Writing to Socket from another method or class

    Hey everyone,

    I've hit a wall with a project that I'm working on and I was hoping you guys might be able to help me out.

    I am creating a socket and keep the socket open to read/write so that the program can react as data is changed live. I created a second class running in a seperate thread that I would like to be able to use the socket in the first class to write data from time. Does any body know how I can do that?

    Kind of what I'm trying to do:

    public class ClassA {
       public void MethodA() {
         Socket socket = new Socket(server, port);
         BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
         BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));	
    public class ClassB {
     public void MethodB() {
      // Here I'd like to either use the BufferedWriter to write to the socket, or some how call a method from ClassA to write to the existing socket

    Welcome to the forum! Thanks for taking the time to learn how to post code correctly. If you haven't already, please read this topic to learn other useful info for new members.

    Pass the Socket object to the other class(es) that need it either:

    1. Through each subsequent class' constructor,
    2. Using a mutator method in each class after the Socket exists, or
    3. Using a accessor method in the class that owns the Socket object.
