Cannot communicate once bufferedwriter is close in java socket programming -

i made server , client java application. should communicate each other through tcp sockets threads. used inputstreamreader , bufferedreader read message, , used outputstreamwriter , bufferedwriter write message. object of bufferedreader called reader, , object of bufferedwriter called writer.

after playing around that, realized socket becomes irresponsive if writer closed.

i closed writer on server side because never send message, read message client only. not throw exception, stuck called methods relate socket such reader.readline() , socket.setsotimeout().

the problem easy solve since don't close writer. however, curious why socket being unable communicate.

the socket becomes irresponsive if writer closed

the socket becomes closed if writer closed.

i closed writer on server side because never send message,

non sequitur. if don't need writer, don't construct it.

stuck called methods relate socket such reader.readline() , socket.setsotimeout().

it isn't 'stuck'. it's closed. must have got socketexception: socket closed when called either of methods. should have noticed that, , should have posted in question.
