java - Do I have to close all resources every time I use them? -

i'm writing chat application in java didactical purposes. of course, met lot of problems i'm not experienced programmer.

basically question is: have close every resource (bufferedreader/writer etc.) after use? if know reuse it?

for example: client waits user input text, can reuse same bufferedwriter or has create every time user inputs , close again?

if want check 1 , same resource multiple times, cloes it, when not utilize anymore. can utilize try-with-resources purpose:

try (bufferedreader br = new bufferedreader(new filereader(path))) { homecoming br.readline(); } grab (ioexception e) {...}
