When to close stream java
Intermediate Java Tutorial - 44 - Closing Down the Streams and Sockets
alright guys welcome to tutorial number
44 and in this tutorial it's actually
gonna be really easy what I have to do
is show you guys how to code the clothes
crap method and remember right here
finally once you're done having your
conversation once you know you chatted
with someone and you had enough of them
you you know close out of the program
and it closes all the crap in Java it's
pretty much the housekeeping stuff what
you need to do when you're done using
streams and sockets all that crap so go
ahead and make a new method outside or
right under your while chatting method
because this is gonna happen once you're
done chatting and we're something that
actually we need to code this first
closed streams and sockets after you are
done chatting looks pretty good
so we'll name this of course don't have
many choices public void close crap you
know obviously we have to build this
ourselves Java would not be ridiculous
enough to name something close crap
although I wish there was a billion
method called close crap because that
would just make my day but anyways the
first thing we want to do is give the
user prompt this says um you know new
line closing connections dot that dah
cuz we ain't done yet alright so this
just you know wow I definitely spelled
connections like that are you kidding me
there you go that's a little bit better
so now we just give them a nice little
prompt that says you know what closing
connections that were we're doing right
now give us some time to do it
so remember when I told you guys that it
would be stupid and also not very good
in programming terms to let the user be
able to type when they're not connected
to anyone well that's the first thing we
want to do we want to shut down their
ability to type so able to type go ahead
and set this equal to false and this is
another small method that we're going to
have to build later on so after this how
do we shut down everything well we
actually need to put it in a try-catch
statement try/catch
and what do you want to catch IO
exception I exception and if we couldn't
shut everything everything down
successfully we'll just go ahead and
print stacktrace
which pretty much shows us our error
message anyways hopefully we're not
going to see that hopefully what's going
to happen is it's going to allow us to
execute this try block which consists of
three very very short lines of code so
the first thing we need to do is we need
to close the streams when we are done
with it
so remember the name of the first stream
that we could send stuff to them was
output go ahead and close this which
pretty much says okay you don't need
that anymore I'm just going to close it
the input stream which pretty much
allowed us to you know receive messages
from the user input closed right like
that and the last thing that we need to
do is we need to close the overall
connection so the socket that's what I'm
talking about
so connection close right there closes
the socket so again this closes the
socket or the main connection between
you know your computer and in another
computer the output causes a stream to
them and the input closes the stream
from them and you basically want to
close things down because if you don't
then it's just going to waste memory and
if you have a bunch of you know empty
servers or excuse me empty streams and
empty sockets sitting on your server
that don't get used then it's just going
to eat your memory over and over and
over again kind of be a waste of you
know memory and resources on your server
or computer so guys good news that's all
you have to do for closing crap down
again what this does is once you're done
chatting closes all the streams and
sockets pretty much good housekeeping
stuff so in the next tutorial we're
gonna be getting rid of you know 90% of
these errors because I'm gonna be
showing you guys how to code that send
message method which basically takes a
message and displays it in your chat
window so enemies thank you guys for
watching don't forget subscribe and I'll
see you guys then
