i have code a chat server and a client with 2 threads in each in server and 2 for client
1 thread will start writing and other thread of client will start listening to the server thread
when this both threads finish the two other thread comes into picture
where 1 server thread is listening for the client and other client thread in writing the message to the server

but my problem is with concurency because when i write in server it appears in client but when i write in client it is not visible to the server unless and until server writes another message
so can you guyz help me this is first time my app contains multithreads

server code


client code

This is issue with go() method of ChatServer, where you are writing to socket first and then creating read thread. Reorder your code and it will work.
