Thanks for your answer! But i can't understand, how to decode ??????????????? ??????????????????????????????? ?? ?

When I send "1" i get string ??????,??3??
or send "ping" i get string ????????????4??????S
or send "hello world!" i get string ????????????f???????#???????o?????

this is special encoded websocket strings? or what?

pseudo code is

InputStream is = s.getInputStream();
byte buf[] = new byte[64*1024];
int r = is.read(buf);
String data = new String(buf, 0, r);
System.out.println("Recieved Data: " + data);

If you are going to send Strings, you don't want to read and write bytes.

BufferedReader br = new BufferedReader(new InputStreamReader(
s.getInputStream(),***YOUR CHAR SET GOES HERE***));

br.readLine();

If the server you are connecting to is using a different character set
you need to use a different constructor for InputStreamReader that sets
the character set. See the docs for InputStreamReader.
