Is there any way that declaring a variable to be of type "Object" and then storing a new Long instance in it would require any more bytes of memory than it would if you declared the variable as type Long?[19:50:45] <svm_invictvs> and my artist gave me an image with 12 tiles[19:51:21] <cheeser> deinspanjer: uh...[19:51:31] *** rlubke has joined ##java[19:51:35] <cheeser> you want to use more memory for Long than is stricly necessary?[19:51:39] <pr3d4t0r> svm_invictvs: Some company in NYC.[19:51:49] <pr3d4t0r> svm_invictvs: I'm about to have a phone call with them in 7 minutes.[19:51:58] <svm_invictvs> ah, cool.[19:52:31] <dmlloyd> deinspanjer: that is sooo implementation-dependent. And anyway even if there were a few bytes difference, it wouldn't be a per-instance difference I'm sure. And even if it *was*, you'd probably need millions of them for it to matter. And even if you had millions, many, many other things would dominate memory usage at that point.[19:52:46] <dmlloyd> in other words, stupid question. :)[19:52:51] <deinspanjer> cheeser: No. The way I understood Java memory allocation, I felt that storing an instance of class Long in a variable declared as type Long would take exactly as many bytes as if you stored it in a variable declared as type Object.[19:53:03] <deinspanjer> But someone else disagreed with me and I'm looking for validation of my understanding.[19:53:26] <ernimril> deinspanjer: objects in java have overhead...[19:53:28] <cheeser> the variable is always 32 bits[19:53:33] *** UK-sHaDoW has joined ##java[19:53:35] <cheeser> the objects they point to have varying sizes.[19:53:36] <ernimril> deinspanjer: one class pointer and one monitor info[19:53:43] <dmlloyd> deinspanjer: the kind of person who would raise something like that as an issue is the kind of person you really don't want to be working with.[19:53:55] <cheeser> so Object o = new Long(5) is the same as Long l = 5;[19:53:57] *** fragsworth has joined ##java[19:54:11] <red-lichtie> deinspanjer: Stroing it a Object is worse, it use the same memory (i.e. Long) and you have to typecast it to Long to use it[19:54:16] <svm_invictvs> pr3d4t0r: er, /msg?[19:54:17] <fragsworth> is there a function to split a string into pieces based on a regular expression?[19:54:27] <cheeser> ~javadoc Strin[19:54:27] <javabot> I don't know of any documentation for Strin[19:54:28] <cheeser> ~javadoc String[19:54:28] <red-lichtie> s/Stroing/Storing/[19:54:28] <javabot> cheeser: http://is.gd/6UoM [java.lang.String]; http://is.gd/iaWp [javax.print.DocFlavor.STRING]; http://is.gd/iaWp [javax.print.DocFlavor.STRING][19:54:32] *** cracki has joined ##java[19:54:32] <deinspanjer> dmlloyd: This pertains to a data structure that is storing many millions of these objects, so yes, a few bytes and reduced overhead can make a difference.[19:54:41] <pr3d4t0r> svm_invictvs: OKi.[19:55:05] *** cracki has left ##java[19:55:43] <dmlloyd> deinspanjer: trying to micro-engineer memory usage is never going to work out for you. Best bet: design it the *right* way first. Then, if a profiler is telling you that memory use is a problem, do something about it.[19:56:02] <dmlloyd> never mind that in a lot of cases, storing millions of anything means you've got a design issue.[19:56:45] <deinspanjer> cheeser: It sounds like you are agreeing with me. It sounds like there are a couple of dissenting opinions here though.. And of course dmlloyd telling me that I'm an idiot.[19:57:00] <dmlloyd> but I contend that it's better to just have a big heap than to contort your code into a twisty mess to shave off a few bytes. RAM is cheap.[19:57:12] <svm_invictvs> *shrug* I woudln't recommend an ArrayList<Long> for something like 64 DSP[19:57:13] <cheeser> deinspanjer: the type of the reference has no bearing on the memory allocated.[19:58:06] <svm_invictvs> dmlloyd: It woudlnt' be unreasonable to store something like a few megabytes in memory for something like a mesh.[19:58:15] *** RLa has quit IRC[19:58:17] <svm_invictvs> That woudl be a few million elements in some sort of data structure.[19:58:41] <dmlloyd> sure.

I know it would take a few extra instructions to handle that, but I was wondering if maybe I might have been missing some extra hidden memory cost to the typecast.[19:59:03] <dmlloyd> I guess if you're getting to the point where you're changing field types in the hopes of trimming a byte here and there, you're taking it too far[19:59:11] <dmlloyd> I guess my point is that...[19:59:16] <svm_invictvs> dmlloyd: Oh, yeah.[19:59:26] <deinspanjer> dmlloyd: I know it can be frustrating to have someone come in here and ask a potentially loaded question when they don't give you lots of background to justify their case.[19:59:41] <svm_invictvs> dmlloyd: I guess I was saying, it depends on your use case.[19:59:59] <red-lichtie> deinspanjer: Can't get much smaller than "long[] values = new long[...]"[20:00:19] <svm_invictvs> deinspanjer: Need to know more about what your'e doing I guess.[20:00:25] <dmlloyd> yeah, long will use less bytes than Long for sure.[20:00:34] <svm_invictvs> fewer bytes[20:00:35] <dmlloyd> in fact I'd never really use Long for most things.[20:00:42] <dmlloyd> svm_invictvs: whatever.[20:00:45] <deinspanjer> dmlloyd: That said, this is an application that is designed to handle variable amounts of data and we have spent a lot of time collectively on the project making sure that we have designed the different pieces of it properly and have memory profiled with many different payloads and such.[20:01:15] *** le_biloute has joined ##java[20:01:24] *** lifecoder has joined ##java[20:01:43] *** romanb has joined ##java[20:01:53] <svm_invictvs> deinspanjer: Do you have an ArrayList<Long>?[20:02:04] <svm_invictvs> that's getting to be a million elements or something?[20:02:32] *** UK-sHaDoW has quit IRC[20:02:36] <deinspanjer> This question pertains to an optimization that was made specifically for lookups of long values. In the cases where this can matter, you could easily require 16 to 64 GB of RAM to execute the process. In one of these cases, the next lowest hanging fruit is making sure that this data structure is efficient.[20:03:12] <red-lichtie> deinspanjer: If you really want to save memory for repeating values use Long.valueOf(long) as it uses a cache for -127 to +128, instead of always using "new Long(value)"[20:03:22] <deinspanjer> svm_invictvs: It is actually a native array of a tuple of Long,Long.[20:03:31] <FauxFaux> I'm almost positive I just saw Sun's server jvm return memory to the OS (like, 2gb of it). I wasn't aware that it could do that, am I insane?[20:04:00] <deinspanjer> svm_invictvs: My argument is that since we aren't using primitives, there is no savings vs having it be a tuple of Long,Object.

Running on 6u12 uses the float ctor of Color though, which leads to an IllegalArgumentException, while running on jdk5 causes no problems at all. Anyone seen similar behaviour?[22:05:43] <Stephmw> r0bby_: yes?[22:05:56] <Stephmw> r0bby_: I work in IT, it's an occupational hazard[22:05:59] <r0bby_> Stephmw: just making sure you know you're a sicko[22:06:09] <svm_invictvs> dmlloyd: RPM[22:06:10] *** Carnage\ has joined ##java[22:06:23] <r0bby_> pot kettle black sureeee but just you have to know it :0[22:06:30] <dmlloyd> bowman: yeah, that's not good.

URL: http://pastebin.com/m2f12c7d <---- I get ConcurrentModificationException on line 34. Any idea why ?:\[22:10:09] <surial> Correction: It should scour the path before doing the 'look in the usual locations per OS' trick. Also, on windows it's not C:\program files\java. It's the location as set in the windows registry. The key is something like HKEY_PROGRAMS/Sun/java/Versions/Latest or something[22:10:12] <bowman> dmlloyd: http://pastebin.com/m3480a14d - this is the spring beans snippet I use. I tried explicitly telling Spring to use java.lang.Integer as the type for the arguments, but that causes a different problem: no suitable constructor can be found. Originally, the 255's are integer values of course, so I have NO IDEA why the float constructor is called.[22:11:07] <svm_invictvs> dmlloyd: oh, i'm a dunce. I forgot to add the repo[22:11:07] <dmlloyd> bowman: oh, yeah it's a spring bug then. Try telling it you want to use "int". It's probably just grabbing the first likely constructor, and the iteration order happens to be different on that JDK[22:11:13] <surial> On macs, the location is not modifiable by the user. os x auto updates just dumps JREs in there, and you can pick what the /usr/bin/java softlink points to in the java settings panel. Which is all considered nice when you need to go find the local JDK to use. It also helps that os x auto update puts entire JDKs in there, not just JREs.[22:11:28] <r0bby_> Meddi: add/remove using the Iterator.[22:11:49] *** LostMonarch has quit IRC[22:11:51] <r0bby_> you changed the state mid-way through[22:11:52] <bowman> dmlloyd: that would explain quite a lot - just like in another project we are testing on Java 6 right now, where PDF fields are shuffled because they rely on the order of a ...

Useful if you need to diff stuff.[23:45:15] <surial> less noise.[23:45:24] <Stephmw> Zvpun: everythine else is pretty much ok (with the necessary caveats for separation of concern, etc)[23:45:58] <surial> marqueed: You saw that?[23:46:33] *** bitshuffler has quit IRC[23:46:43] <marqueed> surial: looking at it now[23:46:52] *** Woflborg has quit IRC[23:47:11] <Zvpun> Stephmw: wait are you saying that I should not call swing stuf in the EDT?

Then, if the class you need isn't there (using a Class.forName() check most likely), load something else, but if it is, new up your special class.
