BufferedReader readLine() blocks

Question

When receiving data using readLine(), even though I put a \"\\n\" at the end of the message using the .flush when sending the message, the while loop that reads my message s

Answer 1

This is because of the condition in the while-loop: while((line = br.readLine()) != null)

you read a line on every iteration and leve the loop if readLine returns null.

readLine returns only null, if eof is reached (= socked is closed) and returns a String if a '\n' is read.

if you want to exit the loop on readLine, you can omit the whole while-loop und just do:

line = br.readLine()
