<0> if i want to reverse Arrays.sort()
<0> what should i make it return
<0> to make it inversed..
<0> u there Clackwell?
<1> return? surely it'd return the same type as you p*** in
<0> return o2 ? 0 : 1
<0> something like that..
<0> if("---".equals(o1) || "---".equals(o2)) return "---".equals(o2) ? 0 : 1;
<0> i use that to make --- be considered "last"
<1> oh, i see what you mean. just swat o1 and o2 sides
<1> swap
<0> yes.. but how do i write it..
<0> can u refer me to a pasting site
<0> where i can paste the code for u?
<1> change your line to have o2 were o1 is, and o1 where o2 is.l
<0> aah..
<0> return collator.compare(o1, o2)
<0> err
<0> return collator.compare(o2, o1);
<0> that would do the trick? =)
<1> why dont you try it and see
<0> it worked yay
<0> thanks talios for making me see the obvious :))
<0> do u know any way to make the column names in a JTable to be clickable
<0> while we are at it :P
<0> also, if i have method(int i), and i use method(); would that make i null or cause error?
<2> o1 and o2 **** as variable name
<0> :)
<0> i only use them temp..
<0> for the Array.sort()
<2> also your condition is ****ed up
<0> what condition?
<2> if("---".equals(o1) || "---".equals(o2)) return "---".equals(o2) ? 0 : 1;
<0> well it works..
<3> if u have a method with signature method(int i) then you cannot call the method without p***ing in an int, i.e. calling method() would not work.
<0> ok, thanks deano..
<2> it works is not enough!!! =)
<0> and, it was MXV (if im on the right network) who wrote it not me :P
<0> whats ****ed up about it Zarathushtra?
<2> are you still working on the same homework?
<0> its not homework i told u :)
<0> its strictly for learning purposes :P
<2> ya ok
<0> today has been good so far.. learned how to use Arrays.sort() to reverse an array :)
<0> my main hazzle is getting the layout for the gui right..
<0> when using JTable outside JScrollPane it strips the headers..
<0> and when using JScrollPane pack ****s it up
<0> anyone here that is experienced with swing?
<4> hello
<0> hi
<4> i'm creating a collaborative whiteboard tool
<4> using rmi
<0> how cute
<4> lol
<4> in the quick tester i wrote up i'm having some concurrency issues...
<0> dont ask me
<0> i cant even get GUI the way i want it..
<4> when user1 draws using a free form pen...and user2 does the same...the drawing gets mixed up...
<4> can anyone give me a general model of how to handle this...
<4> i'm using the graphics context
<0> well ur reading their input as the same obviously..
<0> :p
<0> or maybe im just a retard like always..
<0> i cant even get written code to work
<0> trying to color every second line grey..
<0> using ready made code..
<0> but ofc im not successful
<0> http://www.chka.de/swing/table/faq.html
<4> not sure what u mean...probably my fault for not making myself clear...
<0> tahts the code if u feel like helping..
<4> say i'm using the mouse to draw
<0> well i guess u have already created objects for each user
<4> are u talking to me?
<0> yes
<4> ok..its just i'm not using swing tables or anything like that...as in the url u gave..
<0> no that was my question
<0> :)
<4> basically this is a drawing program and one of the tools allows you to draw using the mouse
<0> i know what ur doing
<4> ahh
<0> but, i ***ume you are creating objects for each user
<4> ok raki..i don't know the answer...but
<4> a few years ago i worked on something similar
<4> and i think the solution was to create a custom table model
<4> google that
<4> or check out http://www.javaalmanac.com
<0> well
<0> read the link i pasted
<0> then go to "How can I have colored cells?"
<0> it shows a way to do it
<0> but i copy pasted everything and added it to the end of my program
<0> but it didnt compile..
<4> what error are u getting>
<4> ?
<0> lemme recomp
<0> starts with extends _D_efaultTable.. etc..
<0> alot of cannot find symbol
<4> that looks like a syntax error...look for erronous capitalization in your code
<0> burnsey
<0> i copypasted the example right off
<0> just copypasted and added it to EoF
<0> can someone please explain how i can sort this matter?
<3> dont copy and paste code when u dont know how it works
<3> understand the code and try to develop it yourself
<0> =)
<0> just want to stripe the damn JTable :P
<3> I have no knowledge of swing etc, I'm a J2EE/web based dev
<3> I would think u would iterate through each row and paint every odd one, but I have no idea of how u would do that.
<0> Deano|Wrk well from what i have gathered
<0> theres some glitch
<0> which makes it harder to do it
<0> which means u should do it like that code i refered to
<0> Deano|Wrk
<0> http://www.exampledepot.com/egs/javax.swing.table/Stripe.html?l=rel
<0> can u see it that works for u?
<3> as I said.
<3> I know nothing about GUIs so I am unable to help
<3> and no, I have no immediately available test environment, nor the time to help to that degree,
<3> like most people here.
<5> There some methods to compare Calendar or Date better than converting to mills, subtracting, then dividing my the time unit of interest? I wanted to compare 2 dates and determine the # days between them....
<3> look at the Calendar API JavaDoc
<3> http://java.sun.com/j2se/1.5.0/docs/api/java/util/Calendar.html
<3> you'll see after() before() etc etc
<3> maybe I should of read the last bit of your question though.
<3> not sure there's a better version than: long days = (date.getTime() - date2.getTime()) / (1000 * 60 * 60 * 24);
<3> but you're not considering any leap days between years, daylight saving time etc
<3> but I suppose Calendar should sort that out via the timeInMillis, and your locale.
<5> I would expect leap days to be considered (using timeToMillis() should)and DLS is not too critical as I only care on the scale of days.
<3> aye as I said
<3> yeah can't think of another way than that tbh
<5> getTime() subtraction results in a numeric value?
<5> I would think I need timeToMillis() instead of getTime() for the math
<5> (well, getTimeInMillis(0 I think)
<3> yeh I'm not sure how Date localisation works
<3> I expect that would be your better choice.
<5> k. Was not sure if there was a better method. I know SQL has a TO_DAYS() function (which is likely just the above math)
<5> no biggie, ok with the math though.
<3> I'm unaware of one in the API
<3> indeed, I too would look for one in the API first
<5> yeah, at 1.5 right now, but def do not see it built in there...oh well
<6> ihu
<6> i need help about java
<7> hello everyone. I am trying to iterate a collection filled with objects that implements an interface. I now wish to delete items form the collection.
<7> i have two objects stored, A implements C, and B implements C
<7> now, using the instance of. how can i find out if there are any onbjects, lets say of A, left in the collection?
<7> my question, is there a way of inverting the statement
<7> if ( iterator instanceof C )
<7> if there aren't any left, then i will not be able to delete items from the collection
<8> http://folk.uio.no/jonmv/inf1010/ukesoppgaver/kodefiler/Uke5.java
<8> why cant one just put the code from the contstructor into main?
<8> *construcktor
Return to
#java
