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 happens because the InputStream is not ready to be red, so it blocks on in.readLine() . Please try this :

boolean exitCondition= false;

while(!exitCondition){
    if(in.ready()){
        if((line=in.readLine())!=null){
            // do whatever you like with the line
        }
    }
}

Of course you have to control the exitCondition .

An other option can be the use of nio package, which allows asynchronised (not blocking) reading but it depend on your need.
