Question

I am trying to use BufferedWriter to send a message to the server from the client or server to client. However nothing will send, but it will listen if you send a message to it. I am not sure what I am doing wrong but I think the problem is from here.

ActionListener buttonActive= new ActionListener(){
            public void actionPerformed(ActionEvent e) {
                messageTextArea.append(textMessage.getText()+ "\n");
                sendText = textMessage.getText();
            }
        };
        sendButton.addActionListener(buttonActive);

    private void startSending(){

        SwingWorker <Void, Void> sendingThread = new SwingWorker <Void, Void>(){
            protected Void doInBackground() throws Exception {

                BufferedWriter writer = null;
                writer = new BufferedWriter(new OutputStreamWriter(connection.getOutputStream()));
                while(connected){
                    writer.write(sendText);
                    writer.flush();
                }
                return null;
            }
        };
        sendingThread.execute();
    }

@trashgod and @madProgrammer gave me a solution using printWriter which works but I want me to make a few more version using BufferedWriter+BufferedReader, OutputStream+ InputStream and BufferedWriter+PrintWriter, however i want to make the BufferedWriter+BufferedReader.

Your code does indeed send data. Maybe the client is calling readLine()? As you aren’t sending a line terminator, it will block forever.

But your code doesn’t make much sense. Writing the same text in a loop can’t be what you intended. And there is no such thing as a PrintReader.
