Can you have an PrintWriter
and ObjectOutputStream
on the same sockets output stream?
out_stream = new PrintWriter(socket.getOutputStream(), true);
obj_stream = new ObjectOutputStream(socket.getOutputStream();
I would say yes but I don't think I would do it.
What is it you want to do?
You can but you have to take care of buffering. A PrintWriter
or an ObjectOutputStream
accepts data, which it converts into bytes, to be sent on the underlying stream (here the socket) at some point . Buffering is about waiting a bit before writing out such bytes, so that the bytes can be sent in "big chunks" rather than individually.
Read the Javadoc about buffering, and use flush()
on PrintWriter
and ObjectOutputStream
when you want to get sure that the bytes get written on the socket.
