i haven't found clear answer on one. i have client/server application in java 7. server , client on seperate computers. client has short (1 line of 10 characters) command issue server , server responds (120 character string). repeated every x seconds--where x rate in configuration file. short 1 second integer.max_value seconds. every time i've created client/server application, philosophy has been create connection, business, close connection , whatever else data. seems way things should done--especially when using try resources programming. what hiccups leaving socket connection hanging out there x seconds? best practice close down , restart or better practice socket remain connected , send command every x seconds? i think answer depends bit on number of clients expect have. if never have many client connections open, i'd leave connection open , call good, if latency issue - on lans, i've seen connections take several milliseconds initialize....
