<0> aha, ok. no clue about streaming.
<1> bummer. :-(
<2> how to print acsii integers in ascii ? example I have the following int x= 0xA; system.out.println(x); prints 10 and not A
<0> if you want to print out chars, why do you print ints?
<0> int is anumber, not a char.
<2> I want to print hex values,
<1> isnt it x.toChar() or something similar?
<0> DaAbz: say another thing
<0> you keep wanting something new in every message. :)
<0> perhaps make up your mind.
<0> and then clearly communicate what you want to do.
<2> I really cant see what is so vague in my question, I've given an example with codes to minimize any confusion
<0> DaAbz: possibly related: http://groups.google.com/groups?complete=1&hl=en&q=print%20int%20hex%20java&btnG=Google+Search&sa=N&tab=wg
<3> i need one of u ****eers to learn me to code ok
<3> so somebody teach me
<2> Clackwell it's much simpler than I thought, Integer.toHexString(14);
<3> no its String.toHexString(14); bitch
<3> for(int i=0; i<java.size(); i++){
<3> System.out.println("You are gay");
<3> }
<1> actually... it hink you can just cast an into into a char... *shrugs*
<1> clackwell... i'v been doing some reading... does this sound about right... i need java to take what i get from the web cam and feed it through a codec?
<0> CppIsWeird: yeah, but he doesn't want the respective char, rather the hex representation of the value.
<1> oh
<0> CppIsWeird: no clue. read up on streaming options for java?
<0> jmf should show up high on the list i guess.
<1> not for java specifically... but in general... im still kinda going through what i'v found and digesting it. does java have specific packages for video/streaming/encodeing ect that you know of?
<1> whats bad is everything i get wants to do it from a file
<1> nothing speaks of from a live source
<1> i think i'll know where to go once i figure out exactly how a codec works
<1> oh ****, im late for college
<1> bbiab
<4> could anyone help me with a stupid problem ?
<4> i'm trying to compare two strings to see if they contain the same text and the compare is failing even though when I output the text to screen it's identical
<4> the comparison is if ( jobname == scheduler[i][1]){
<4> any ideas ?
<5> you can use the "equals"
<5> in the string cl***
<4> forgive my ignorance here but could you show me what you mean ?
<5> there is a method, but i don't remember how exanctly it was
<5> something like if(jobname.equals(scheduler[i][1])
<5> if(jobname.equals(scheduler[i][1]))
<5> it returns true if both strings are the same
<5> try it
<6> what's an ordinary way to compare two Strings ?
<6> to check if they are identical even
<4> alb_bd you may just be a god :)
<4> second question
<4> is there any way within java to autovivify an array ? by which I mean is there any way to create and use and array without first specifying it's size?
<7> no
<4> what about expanding it's size if more space is required?
<7> you can write a method that creates a new (larger) array and moves content over, and then changes the object reference.. Or use a collection
<4> what about creating a m***ive array and then compressing it down?
<7> same issue, once an array is created you can't change its size
<6> Oh common s/he's asking about some sort of Array object or how you call it in JRE
<4> what would the opposite of .equals be?
<7> ?
<5> equals returns a boolean if you want the opposite it could be !string.equals(...)
<4> if i use thanks :)
<8> Is there anyway to p*** a cl*** (not an object to a method). Something like method(x) { Object o = new x(); }
<8> ?
<9> you want a template
<8> if that's close in concept to c++ templates, no
<9> er
<9> sorry
<9> I thought I was looking at #C++ haha
<9> hm
<9> Generics maybe?
<8> no, i solved it
<8> Cl*** x
<9> hm, all right :)
<8> but new x(); doesn't work, x.newInstance works (that's what I was missing)
<8> :)
<9> ah
<8> when I call a method that has a Cl*** parameter
<8> can i simply use a cl*** name
<8> like public method(Cl*** c)
<8> if i have a defined cl*** x
<8> can I simply call method(x); ?
<9> you want to call a static method from the cl*** itself?
<8> no i want to instantiate it
<8> actually, i have an abstract cl*** let's say Shape
<8> which can be either a Square or a Circle
<8> I have a cl*** World in which i have a Shape x;
<8> in the World constructor i want to p*** a (Cl***<? extends Shape> cl)
<8> and in the constructor: x = cl.newInstance();
<8> does that make any sence ?
<9> hm, have to say I don't know, sorry
<8> ok, sorry
<8> i'll manage
<8> thanks though
<9> could have watied for someone else, heheh
<4> is there any way you can delete a array ?
<10> if you set its reference to null, the vm will take care of garbage collection
<10> but here is some information on how to force it, http://java.sun.com/docs/books/tutorial/essential/system/garbage.html
<11> using java in general is a bad idea from what i've heard
<10> why is that SB_ ?
<11> slow
<11> and not very useful
<11> like, for some things it does stuff
<12> SB_: you are totally off the track
<11> but if you are trying to do anything serious
<11> :)
<11> kinemaway, i guess i just don't use java that much
<11> actually, not ever since my cs cl***
<12> and in business, development time is more important than execution time
<12> you simply buy hardware to compensate
<11> guess so
<11> yeah
<11> that _might_ work
<11> ok
<12> lol, it will take 3 weeks to develop instead of 3 month
<11> so it sounds like you use it for work
<11> what do you make with it at work
<12> so adding the 1000$ for an additional server is way worth it
<11> like, what would be an example application
<13> well I've been working on a API that allows you to manipulate objects constituating knowledge resources pluggeable in the company new web index initiative
<13> with the editors calling the services from the API etc
<11> oracle?
<13> optimizing the code is nothing to optimizing the design
<13> and I measure performance with the big O notation
<11> um... ok?
<13> which lead to real optimization (order of magnitude)
<11> But why not juse use oracle
<13> my API calls Hibernate which abstract database vendor
<11> or php/mysql
<13> so I support about 15 databases
<11> or something like that
<14> Question: Is it good design to have a driver program -> Encapsulating Cl*** -> Objects?
<14> I completed my homework, I'm just wondering what the best design is for personal info.
<11> kinematix, so you are writing something that is a java interface to go over multiple OS then basically
<14> I created my driver which uses a cl***; the cl*** stores the head / tail for a linked list and manages it.
<13> because I need a domain model, I need stateful objects, I need concurrency management, I take advantage of the huge java portable cl*** library
<14> The cl*** uses another cl*** which is the data, list pointers, and accessor / modifier methods
<11> kinematix, i guess?
<11> kinematix, seems like java is very limited
<13> multiple OS, multiple database, and the API may be called with web services (from a C# program let's say)
<11> C# :P
<13> java isn't limited, it is a full featured language
<11> it's not limited by that
<14> (with an ugly ui)
<13> we have no operator overloading, no multiple inheritance (but interfaces, alot better according to me), we don't have pointers, but we have references
<11> like there are multiple ways to do most problems right kinematix ? it seems like one could easily use multiple other things in place of java that would work better
<13> you don't need pointers in 90% of C(++) code, that's just a trend
<13> you could use references
<11> Who said that 90% of people use pointers?
<13> SB: if you are designing a simple dynamic web site you may use php + mysql
<14> Can anyone answer my (simple) question? :(
<13> that would be better yes
<13> sb_: me
<11> or that 90% of pointers are used incorrectly though
