<0> C++ is a great language but modern C++ looks like a keyboard threw up
<1> how do you find out the size of an object in java ?
<0> toucan: why do you find out the size of an object in java?
<1> so that you don' t run out of memory when dealing with large amounts of data
<2> toucan you can't, it's an issue, but a harder one than you think, if you already kniow the size, then you have it in memory, therefore you haven't run out
<2> problem is: whuile creating an object you run out of memory, then you're stuffed
<2> -u
<1> so i take it there isn a sizeof operator ?
<1> isn' t
<2> no
<1> ok thanks
<2> and as I pointed out, it won't help you
<3> it almost seems like c++ developers don't need google.
<3> i would be jealous, if it wouldn't be for the language. ;)
<1> is it normal for a java program that creates one million strings of 6 characters each to take up 255 meg of memory ?
<2> no
<1> or is the JVM just reserving as much memory as what one set as the max heap size?
<2> are you setting -Xmx*** cmdline option ?
<2> read the toll doc for that behaviour
<1> no, i only have that set in the IDE config file actually
<3> tool docs
<2> one of the -X settings is the initial size
<3> inside the java documentation
<1> when running from the command line, i' m not using any options at all
<2> then the max memory should be 64M for the heap

<3> hallo bryin
<2> hi
<4> oops I missed talios and Thunder^
<5> 'lo Bryin
<5> Bryin, go to parachute at all?
<4> talios: Nope - been to Tga yesterday for a server install
<4> and Saturday was too hot to do anything
<5> tell me about it
<5> I thought about going for the day and just melted and gave up
<4> Actually I went to Mt Maunganui & Pyes Pa yesteday
<5> screw sitting outside in that heat
<4> yesterday
<4> yes, it was worse on Sat
<4> 33.2C
<5> :( I had 31C here at 11pm :(
<5> 11-freaken-pm and STILL 31C :(
<4> yep, same in Hamilton - I think it was slightly higher
<2> sounds like summer here
<5> calchas, if it wasn't for the 88% humidity it might have been nice
<5> air was soooo thick and damp
<4> pffft
<5> it was like walking through a steam room all day
<4> you should have been in Hamilton
<4> we had 90% humidity
<4> and on Saturday, 97.0% humidity
<5> :(
<4> it's 83% humidity here NOW
<4> and 22.6C
<4> at 9am in the morning!!!
<4> at 7am it was 90% and 21C
<5> :(
<5> I should get a thermostat - I get alot of different values than the metservice which just records the airport
<4> talios: I use a guy's weather station down the road
<4> he uploads the detail to wunderground
<5> cool
<5> whats wunderground? I guess weather-underground or something?
<4> yah
<4> same baby
<5> never heard of it....
<4> http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=IWAIKATO4
<4> that's his station
<4> theres a few others, like Cambridge & Te Awamutu etc stations around
<4> but I don't know the guys who run them
<4> oh and Raglan too
<6> hi
<3> hi caver
<6> http://www.geocities.com/javacaverdude/beginning.html this is a new article headings I'm proposing to write, tell me if you like the points of discussion..
<3> caverdude: i don't understand the contents of that page. :)
<6> I'm about to begin writing on those points
<7> Hello!
<6> half baked ideas :)
<6> hi
<7> Anybody know how to write a string to a file? then append an other string to a file?
<6> basing it on my current level of experiance with my projects, which is still not great, but I have learned a few things
<3> lolol: http://www.google.com/search?complete=1&hl=en&q=append+text+file+java&btnG=Google+Search
<7> 10x :)
<7> many kisses :P
<3> lolol: thank me by using google next time.
<7> hehe :D
<6> Clackwell I have determined from my point of view that OOP has a (to use as a medaphor) grain, or resolution to it.
<6> maybe not just OOP
<6> maybe anything
<6> but anwyway
<6> if a developer chooses a course grained approach he might save initial time, but later on the app will require a finer grained approach.. too fine of a grain and you spend way too much time getting started..also too fine of a grain means overuse of OOP and heavy on system resources
<3> caverdude: unless you can predict future requirements, aiming to solve the problem with minimal effort, building the simplest solution that will possibly solve the problem, seems to make sense to me.
<6> Clackwell yes, this means using course grained approach in using my medaphor
<6> or low resolution
<6> hoever you want to look at it
<6> however
<3> coarse, i believe
<6> ya
<6> but sometimes you may have some foreknowlege of the problem domain and in the design, in this case you might begin with a medium grained approach
<3> high complexity without a good reason for it vs. just enough complexity as necessary to meet the known requirements.
<6> yup
<3> yeah, but in my experience it always makes sense to doubt the foreknowledge. also some people may add complexity for the sake of flexibility, while not having any good reason to ***ume that the flexibility will ever be needed.
<6> true
<6> this is what I'd call too fine of a grain
