<0> I have a String[] tempString Array
<0> In that Array I have an InputString Value containing a 'sentence' followed by a URL
<0> I want to store the 'sentence' and the 'URL address' into two separate array.
<0> In doing so, I'm getting this error.
<1> so did you make those two new arrays with size of current array?
<1> tempString.length or something
<0> I sure did.
<1> well where are you trying to use -1 as index??
<0> int splitNumber = tempString[k].lastIndexOf("http://";);
<1> heh.. well if http:// isnt there, it returns -
<1> -1
<0> description[k] = new String(tempString[k].substring(0,splitNumber));
<1> so do that if (splitNumber != -1)
<0> ok.
<0> if my Input is .....
<0> help out help come in http://www.yahoo.com
<1> should find http://
<0> It should make an Array[] of {help out help come in};
<1> im telling you -1 is returned where there aint no such substring in indexOf
<0> Hmmm....
<0> I see.
<1> println each string and see
<1> why
<0> Well it should get the Index of http://
<0> as soon as it finds out in the InputString
<1> println each string and see why some strings dont have http://
<1> perhaps it's also case sensitive?
<0> Case doesn't matter here.
<0> Everything is in lowerCase
<1> ok
<2> write a test case in JUnit
<2> do it for only those 3 or 4 lines
<0> Ohh well, that'd take sometime.
<2> not really
<1> niTew[]lF: well println each string before indexOf
<1> and also println if it is -1
<2> if you're using an IDE it's quite fast
<1> or just println when it is -1
<1> and see when it fails
<0> Alright
<0> I don't get it man.... Its a freaking PAIN.
<1> hehe
<3> This is a bit of a stupid question, but the books aren't really helpful. I've written an abstract cl*** say, FileOb, in FileOb.java, and extended it to TXTFileOb in TXTFileOb.java . But the latter will not compile cleanly - I get the "cannot find symbol error". The book I am using describes all inheritence matters in the context of a single file. What am I doing wrong?
<1> are they in same package?
<3> wolfey: They are in the same folder - I haven't packaged them yet.
<1> are you trying to access private variables of supercl***?
<3> wolfey: No.
<3> I declared no attributes as private
<3> I suppose the default is public...
<3> I am certain it must be something so simple.....
<3> public cl*** FileOb {...........................}
<3> in FileOb.java
<1> ksk_BRB: you can paste both files to pastebin.com
<1> :P
<1> and let us see
<3> and public cl*** TXTFileOB extends FileOB {...........................}
<3> is that right?
<1> yes
<1> well doesnt it say in which line?
<3> sigh
<1> it doesnt find symbol
<3> I get a number of errors
<1> always start with first
<3> one is that it cannot even find FileOB
<4> default is package and your package statement should be the first line of code in your programs
<1> well if it cant find FileOB, it's logical that all else is error
<3> sabre: I did not use packages. Wont TXTFileOb find FileOb in the same folder it is in?
<4> ksk_BRB: dunno..always package stuff here
<1> ksk_BRB: when you give up, paste both files to pastebin.com and show us
<1> :))
<3> Sure
<3> wolfey, sabre: I put it up on pastebin, under kkaisare
<1> give us url
<1> it generated one
<3> http://pastebin.com/659737
<3> You'll notice I included my compilation attempts at the end.
<4> Note: FileOb.java uses unchecked or unsafe operations <-- wtf is that?
<3> sabre: That is a warning generated by jdk1.5
<3> sabre: Compiles cleanly under jdk1.4
<4> ok did you try to do whta it said?
<4> ahhh
<4> Note: Recompile with -Xlint:unchecked for details. <-- prolly need to do that
<3> sabre: Did before. No change. I am so sure it is this small timy thing I've overlooked.
<2> I'll try here under 1.5
<4> ksk_BRB: the subcl*** will not compile unless the super cl*** does
<1> ksk_BRB: names are case sensitive. and if you dont provide () constructor in super cl***, you must do same constructor in derived cl***: http://pastebin.com/659752
<4> that makes sense
<1> ksk_BRB: feel free to declare public anythign u want
<1> i commented some stuff to compile in single file
<5> why is this warning: D:\Development\Java\Studio Enterprise 8\Komodo\src\Utils\FormDefinition\Fields\Transfer.java:49: warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.ArrayList
<3> sabrewolfey: Which line nos, did you change?
<1> ksk_BRB: all that contained FileOB
<6> Sancy : google the error msg to get some background
<1> commented out second include's and all package
<5> ok
<1> changed cl***es to protected
<1> but especially 157
<1> and 147
<1> that was wrong
<4> errrr prolly wanna just go public
<1> well i removed public so i had single .java
<1> doesnt change much
<2> changed the constructor and BufferedFileReader can't be found here. Rest works
<5> got it how to solve it :D
<1> sticazzi: yup
<4> definitely don't use default(package)...it is the most restrictive in many ways
<3> wolfey: Looking into it.......
<6> g8t , Sancy
<3> wolfey: Why do we need that constructor?
<1> ksk_BRB: because you dont provide () constructor in supercl***
<1> only (String) one
<3> @@
<1> ksk_BRB: dont take it too hard
<1> :))
<3> Wait a minute, does that mean I should comment out the constructor in FileOb?
<1> no. it means it makes no sense to construct FileOb instance without file
<2> TXTFileOb(String filepath) {super(filepath);}
<2> if you use that as a constructor it makes sense
<1> sticazzi: i did same ;)
<2> technically speaking I didn't do it. I let Eclipse fix it for me :D
<1> i used gnome editor
<1> didnt wanna bother with importing to NetBeans
<2> I used to use NetBeans, don't know why I switched. Netbeans has a good swing designer, though
<1> well eclipse is a bit more pretty
<1> :))
<7> sticazzi, you can get matize for eclipse
<7> its the netbeans gui designer
<2> ahh, nice :-)
<3> wolfey: Hmm, I am still getting the same errors...
<1> mmmm
<1> and one thing, if you want to use package, you must run it from outside package dir, with java package.Cl***
<2> Rob_uknow, do you have a link to it? can't find it with http://www.google.com/search?q=matize
<7> http://www.myeclipseide.com/ContentExpress-display-ceid-77.html
<3> wolfey: Under what circumstances would TXTFileOb not be able to find FileOb?
<7> ofcourse eclipse offers the visual editor already
<1> 1. if you use different cases for chars... java is case sensitive. 2. if they are not in same directory AND package
<2> visual editor isn't that good
<3> Can you see if it works for two files? separately, I mean?
<2> ksk_BRB, I did it in two files to start with
<1> ksk_BRB: http://86.61.12.211/fileob/ compiles
<1> dunno if it works
<1> oh and make second cl*** public:P
<8> I am trying to read a file convert it to a double and ***ign it to an array here is what i got so far http://pastebin.com/659851
<8> any help would be appreciated
<7> I can kick you
