How should I read from a buffered reader?

Question

I have the following example of reading from a buffered reader:

while ((inputLine = input.readLine()) != null) {
   System.out.println(\"I got a message from         


        

Answer 1

When the socket on the other end is closed, the reader should return a null string. This is the condition that you are looking for. To handle the exception, wrap the reading loop in a try/catch block.

 try {
   while ((inputLine = input.readLine()) != null) {
     System.out.println("I got a message from a client: " + inputLine);
   }
 }
 catch (IOException e) {
   System.err.println("Error: " + e);
 }
