hello, I'm making a client-server program in which i'm sending a String from client side using DataOutputStream & receiving it on the Servervside using the following code: InputStream in = request.getInputStream(); BufferedReader r = new BufferedReader(new InputStreamReader(in)); StringBuffer buf = new StringBuffer(); String line; while ((line = r.readLine())!=null) { buf.append(line); } String s = buf.toString(); But in the output i'm receiving is appended with the "+" operator.What i should do If i want to print the String in the same manner as I sent it,i.e. with More>>

hello,

I'm making a client-server program in which i'm sending a String from client side using DataOutputStream & receiving it on the Servervside using the following code:

			

			

			InputStream in = request.getInputStream();
			

			

			BufferedReader r = new BufferedReader(new
			

			InputStreamReader(in));
			

			

			StringBuffer buf = new StringBuffer();
			

			

			String line;
			

			

			while ((line = r.readLine())!=null)
			

			{
			

			buf.append(line);
			

			}
			

			

			String s = buf.toString();

But in the output i'm receiving is appended with the "+" operator.What i should do If i want to print the String in the same manner as I sent it,i.e. without the concatenation operator?

Thanking you ,
Jignesh

I'm suspicious of the DataOutputStream. Is there any reason that you are using it as opposed to a BufferedOutputStream?

Since you are sending character data (strings) you probably also want to pay attention to character encoding.

Client:


PrintWriter out = new PrintWriter(
  new BufferedWriter(
    new OutputStreamWriter(
      getOutputStream(),
      "UTF-8"
    )
  )
);
out.println("My Line");
out.flush();

Server:


BufferedReader r = new BufferedReader(
  new InputStreamReader(in, "UTF-8")
);
String line;
while ((line = r.readLine())!=null){
  buf.append(line);
}
String s = buf.toString();
