<0> sorry
<1> is there an exception
<0> Exception in thread "Thread-4" java.lang.NullPointerException
<1> MatrixEVT just stick to answering the questions and not embelishing
<2> "java.lang.Cl***NotFoundException: HellowWorld.cl***
<2> "
<0> yes
<3> :::)
<1> you don't have all the language required for this discussion and I'm trying to work round that
<1> MatrixEVT at last, why isn't it found (maybe the cl*** file doesn't exist, or is in the wrong place)
<3> ::)
<1> see what teralaser said
<0> ok
<0> thank you
<0> it works
<0> thank you a lot
<2> Weeee :)
<0> sorry for my misspelling ;)
<3> MatrixEVT: to begin it is hardest.
<1> MatrixEVT properly reading the exceptions is a huge part of finding what's wrong. It may help you to use the appletviewer in development
<4> It would help more to write normal applications instead of applets.
<1> yes, and my comment fits there also (less appletviewer)
<1> :)
<0> how to get appletviewer?
<3> it's part of jdk
<0> ok
<0> thanks
<5> Ooooohhh . . . Nice... Anyone here have experience with JFace/SWT?
<6> Hi
<5> 'lo
<6> every1
<3> DSpair: not me
<5> Thanx wolfey... I'm reading up on it, and it looks like EXACTLY what I need for the app I'm writing, so I thought I'd ask to see if there were any "gotchas".
<7> Seems like a nice but brief review of 'Thinking in Java rev. 4': http://www.regdeveloper.co.uk/2006/04/07/thinking_java/
<4> Everyone knows that Java programmers don't think..
<8> rickety: Why don't they think?
<7> sure they do, but about totally different things I bet :)
<4> I was just looking at "Thinking in Java" and trying to be sarcastic..
<3> rickety: i read some heavy bashing against java.. that java makes stupid programmers... however as in any language, you must understand algorithms to write good code.
<8> I've been using Java for two years now, and am beginning to take a dislike to it.
<3> and i can do things horribly slow in C as well
<3> :))
<4> Disliking a programming language is normal.
<4> The reasons are more interesting than the actual dislike.
<8> For some reason, Java comes across as a "MBA" language. Using it is remarkably similar to telling a cl*** - Do this. And to another - Do that... Pure Delegatorial Paradigm.
<3> i'm doing java for 5 years. i love it... when i did algorithms exercise i first did in Java, then transformed it to C++.. while C++ code wasnt really faster. it took 5x more time to debug.
<3> doesnt this tell it all?}
<3> :P
<8> wolfey: Didn't quite like C++ either.
<3> AbsentTone: what do you like?
<8> Loved C. Lisp sounds almost orgasmic, but I've yet to plumb her depths.
<9> Lisp is fun stuff.
<9> Takes some time to get used to the way it works, but once you do, it's pretty neat.
<3> i took a brief look at Ruby, now that language is quite ammusing
<8> Resonator: And a couple of tests sugges t that Scheme is No. 2 after C in terms of speed.
<9> C++ *yarf* Objective-C - much nicer!
<9> I have to admit all my Lisp was done within emacs :)
<3> geez emacss:P
<8> Resonator: I've taken a shine to SciTe myself.
<3> emacs is too hard :P
<9> I do just about everything in Eclipse now. But if I'm doing something other than Java, I usually have an emacs session running to handle it.
<9> It's hard to learn, but insanely powerful once you do!
<4> vim
<3> for java: NetBeans
<7> hmm.. I'm a vim/Netbeans guy :)
<8> wolfey: Never really got used to using an IDE proper.
<3> AbsentTone: you didnt use it long enough
<4> wolfey: The above thing about debugging could just mean that you're a crap C++ coder.
<3> rickety: well definetly i code way better in java.. but pointers instead of collections and manually deleting items....
<3> i didnt learn much more C++ than necessary to p*** college exam
<4> There is STL for C++, and you can get garbage collectors for it.
<3> i spent great deal to learn java
<8> wolfey: True. But then I tool a while to wean myself from Turbo C++ YUCK..... Never trusted an IDE since.
<4> I'm not defending C++, just attacking you.
<3> rickety: yeah... i should look at STL, definetly.
<3> rickety: i dunno.. i wasnt interested in c++ that much
<3> java was love at first sigth
<3> i do c++ when im told to do in c++
<3> for fun i always do java
<8> C++ tries to be too much to too many. C is good for systems code. I like to use it for that alone. Lately, I've been using Java for a few small apps - Satisfactory, but it isn't a relatonshoip I'm proud of.
<3> why not AbsentTone ?
<3> java is quite perfectly design, according to patterns
<8> wolfey: I guess I haven't quite bought into the whole OOP thing.
<3> well OOP simplifies development of not-time-critical stuff
<3> since i dont do such stuff, im very pro OOP
<3> good OOP makes user apps less buggy
<8> wolfey: I agree. But I wonder if it is solving the right problem.
<8> Lisp appears to do that. If it had a good librabry base that was consistent in implementation, we might have seen more of it.
<8> Java lets me handle complexity by building smaller proglets that specialise in a given function.
<8> But it does so by taking away some flexibility. I experienced this while trying to build a search engine.
<8> The data structure I had in mind would have been very very fast if developed in C. But using Java forced me to use ArrayLists, which knocked my stuffing out in terms of speed.
<3> what structure?
<3> i normally use combination of vectors and hash tables.
<3> that is never too slow
<8> wolfey: I'll spill the beans in June. For now, settle for "a 37 dimensional hyperpolygon" God that sounds so smart! :D
<3> WOV:)
<8> wolfey. It is ridiculous, brother. Just a smart way of saying someything very simple, yet necessay if you want to get an Engineering Degree. Stupid profesors.....
<3> ;)
<8> Vectors are a good idea. But if you must use them as a primary ingridient, you might as well use C and pointers, they are at least faster.
<3> well vectors are used to obtain something by index or to iterate in entered order
<3> while hashtables to get object from some other data
<8> Java rocks when it comes to using its Collections - which is a good way of building simple standard apps. But if you want to step out of the norm, I'd go for C - or Lisp, if the performance is adequate.
<3> i oftend did one vector and many hashtables to point do data in vector
<3> for now i did only standard stuff, i was lazy student:)
<3> lisp.. next year?
<3> :P
<3> i think
<8> In someways, Java seriously manages to raise the competence of the mediocre programmer. But it offers little to those who have specialised requirements. C still makes me giddy.
<8> wolfey: Lisp/Scheme is good, but look at Haskell too.
<3> will see.
<8> Heard some very nice things about it.
<3> well java is ideal for toys and business apps
<4> This is sheer rubbish.
<8> wolfey: Business apps - hard fact there. Java is more of a technology language.
<8> Very very buzzword oriented.
<3> AbsentTone: i've seen business apps in java
<4> JEE is very buzzword-orientated, yes.
<4> JSE is very very good on performance.
<4> Dropping to C for performance reasons is usually a dumb thing to do.
<8> wolfey: I am agreeing with you, not contesting you.
<3> AbsentTone: my former employer was doing Java engine with scripts to clone existing Cobol app
<8> wolfey: I am agreeing with you, not contesting you.
<3> thanx
<8> rickety: Trust me, Java made me cry when I tried to build my DS. My C prototype worked sweetly though.
<4> A bad Java programmer and a bad C programmer will make bad software. They'll both run the same speed, and the Java one will work first.
<3> rickety: !!!:)
<4> A good Java programmer and a good C programmer will make good software.
<8> Java saves time, at the cost of flexibility. I'd use it for no more than the simplest app-sets
<4> A good C programmer compared to a bad Java programmer is a waste of time and vice versa.
<4> Even if it's one person doing both.
<4> AbsentTone: What flexibility does Java lose?
<3> AbsentTone: well dunno i think you dont know enough OOP to be flexible
<10> AbsentTone: don't even try to compare java's flexibilty with C's
<3> AbsentTone: go read some patterns book
<3> :)
<3> abusive
<0> i installed jdk and don't know where the appletviewer is
<0> never mind
<3> AbsentTone: you can do it very flexible, however very CPU and memory consuming
<8> rickety: I found it much harder to build my DS in Java. wolfey: Yes, Iam not much of an OOP guy.
<10> C is good for missle launching apps...that's it :)
<8> sabre: lol
<8> True enough.
<10> when pushing the nuke button i want an app in C and not java
