I'm new at sending data through sockets but I figured out how to do it now. My problem is that I can only send and receive bytes, is there a way that I can send and receive strings in stead of bytes? Or is it always bytes?
I'm sorry for my bad understanding of how sockets work but I'm trying (;
Thanks in advance!
You can use DataStreams and writeUTF. On the other side you can read the Strings with readUTF.
yourSocket = new Socket("yoursocket.ip", port);
os = new DataOutputStream(yourSocket.getOutputStream());
os.writeUTF("your string");
On the other side you can read it the same way with
is = new DataInputStream(yourSocket.getInputStream());
String yourString = is.readUTF();
To send data over a socket, it must be a byte[].
Using the <string>.getBytes() method, you can retrieve a byte representation of the string. The resulting byte array can then be sent over the socket. On the receiving end, use the String constructor String(<byte array>) you can re-create the string. Both of these methods allow you to pass a character format as the second parameter (have a look at the JavaDoc). I'd recommend doing this as to make sure that, even on two different platforms, you recieve the same data.
