class ReceiveThread extends Thread {
    SocketChannel client = null;

    ByteBuffer buffer = ByteBuffer.allocate(50);

    private boolean val = true;

    public ReceiveThread(SocketChannel client) {
        this.client = client;
    }

    public void run() {
        while (val) {
            try {
                while (client.read(buffer) > 0) { //此處程序進入無限循環直道滿足條件
                    buffer.flip();
                    String result = decode(buffer);
                    System.out.println(">" + result);
                    buffer.flip();
                }
            } catch (IOException ex) {
                ex.printStackTrace();
                return;
            }

        }
    }
