BufferedReader ReadLine冻结程序

Question

My code is as follows;

When i use BufferedRead readLine() the whole program gets frozen. the problem is that readLine will rnot return the line until it reaches the end of the line. because the server will not send a new line char value it will not close.

So how can i get over this ? Please edit my code;

                  while (ok) {
                        BufferedReader re = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                        aString = re.readLine();
                        ...
                    }

note: i want to do this programatically, and not go and kill the process that's running it

UPDATE

StringBuilder re= new StringBuilder();
                    while ((c = r.read()) >= 0) {
                            re.append( (char)c ) ;  
                    }
                    String result = re.toString();
                    byte[] contentInBytes = result.getBytes();
                    out.write(contentInBytes);
                    out.flush();
                    out.close();

Don't use the readLine() method of BufferedReader . Use the read() method, which will read individual characters. You'll have to convert them from ints to characters, but that will get you around not having a newline character to read.

EDIT: Adding Assuming "re" is your buffered socket input stream reader...

while ((i = re.read()) != -1)
{
   if (i > 0)
   {
      char c = (char) i;
      // Do something with the character
   }
}

END EDIT

Additionally if you are concerned about the server not responding, then you may want to place a timeout on the Socket :

socket.setSoTimeout(milliseconds);
