Considering these questions,how one can make sure he is making a correct choice from the available answers for the scenario asked? Questions: What is the most appropriate method for read a line from a file and to store it in a String object? I have a socket handle s. I want to read data a line at a time from the remote network using this socket handle. what is the most appropriate choice I can use? Regards, Vinod

File and socket, doesn't match, so the question doesn't make sense. If we leave out "File", you can try thinking it through like this: First thing, look at what you have. That's a Socket here. The only usable thing it offers is an InputStream: s.getInputStream() If you want to read data "a line at a time" we're talking about characters, so it would be nice to use some XxxxReader. This Reader should be able to work with what we have (InputStream), so why not have a look at InputStreamReader: new InputStreamReader(s.getInputStream()) We want to read "a line" (at a time), probably more than one altogether. We can of course write some loop reading character and check for some line-ending characters, but perhaps we can avoid this by using some Buffering stuff ... BufferedReader fortunately offers a method readLine giving back a String :-) BufferedReader b = new BufferedReader(new InputStreamReader(s.getInputStream())); String line = b.readLine(); � voil� :-)
