 | If you compile a small application with debug info using BC55 you can then load it into TD32 and use that to step through the code line by line like you would a debugger in an IDE. If there's no debugging info you'll get assembler code instead. |
| | That or use NumberFormat. To any sane person (and a computer in that regard is a sane person) the leading zeros are utterly unimportant, a darned nuisance even, and thus stripped and ignored. None of you except sos realised that apparently. None of you took the trouble to actually look … |
| | Think about what you're doing: You want to call a method on a class, so you'd better make sure you have an instance of that class. In this case that class is an inner class to another class, so you must first have an instance of that other class. That … |

| | if you can read one file you can read them all...  |
| | Re: uknown sender and such things are used exclusively by spammers and conveyors of trojans and other malware. I've never yet seen a legitimate reason to want to send an email in a way that can not be traced back to the sender.  |
| | Well, you're just failing to read the data from the resultset and set it to the right fields in your datastructure, and/or failing to map that field to a column in your jTable. But as you don't tell us what you've actually done it's impossible to say which of those … |
 | We're free to choose, but Ifni is unpredictable. And even if everything were predestined, those deciding that destiny (the very fact that you believe in predestination means you believe in some deity or other) had the free will to decide on that destiny and therefore free will still exists (it's …  |
| | your rant shows that the government was correct in turning down your proposal. It stinks of incredible immaturity and an utter lack of capacity for analytical thought which can only mean your plan is not feasible, certainly not when executed by you.  |
| | There are in fact more, there are books that actually teach skills rather than just cram your head full of exam answers :) Look for Head First Java (Kathy Sierra and Bert Bates) and Agile Java (Jeff Langr), both excellent tutorials that teach you well. Then there are the books … |

 | Re: 51 [QUOTE=christina>you;354623]But really, what exactly do they do there?[/QUOTE] That's secret... Some keywords: black helicopters, THEM, the man from UNCLE, MK Ultra, chemtrails, fake moon landings. Technically Area 51 is a military grid coordinate for a part of the Nellis ranges, which are most famous for their use as bombing and …  |
| | And don't try to write C code in Java. C and Java have completely different paradigms, C being procedural and Java object oriented. Java in fact has more similarities with Smalltalk and Delphi than it does with C. Just about the only things that are similar to C is actually … |
 | what "null value"? It's highly unlikely the ResultSet will be null, though with that bad driver you're using it could maybe happen (as it was never intended to be more than a technology demonstrator, and possibly poorly written). The database could contain NULL values for you to retrieve, if so … |
| | NoClassDefFound isn't thrown from the compiler, only from the runtime... So you probably did not in fact compile your class, or indeed forgot to include it on the classpath when trying to execute it. |
 | use a version control system to keep track of changes, that way you can always revert back to an earlier version. And oh, an 800 line class is almost always way too large and is just asking to be split into different classes among functional lines. |
 | not something you'd use JSP for anyway. A background process started from your crontab would be the most logical choice, or alternatively an autostarting servlet running a background thread if the functionality is an integral part of a web application. |
| | no ketchup for me, anywhere. Maybe a splash of curry sauce on a burger, but that's as far as it goes.  |
 | anyone wanting to turn Java code into native Windows executables should be shot on sight. It's useless. |
| | we've heard all the crybaby stories before, Curtis. He was quite correct when he said that your question was incredibly basic. Any introductory tutorial would have given you the information had you cared to look. What will you do next? Come here for every single thing you don't immediately understand? … |
| | The entire page context which includes the request parameters is available to the included page. From the standard work on JSP (Hans Bergsten's book published by O'Reilly, 3rd edition, page 560): [quote] All other request unformation is also left untouched, so the target resource has access to all the original … |
| | weird requirements, clearly some homework assignment for learning SQL rather than a serious commercial project (or if it is, quit that job instantly). The entire thing makes no sense at all. If you already have the ballance in the database (very bad, no real database would or should do that) … |
| | But do remember to use proper capitalisation, interpunction, spelling, and grammar. If I saw the style you just used in your resume or cover letter it would get instantly binned.  |
| | I wonder what happened to his documentation set which he'd have had if he'd bought the thing... |
| | Re: Pet Petition more idiot online petitions by kids who can't think for themselves and instead buy every screaming rant by PETA. Their definition of "animal cruelty" is depriving animals of anything at all. In fact their ultimate goal is the extermination of mankind in order to leave the planet to the animals … |
| | use the welcomefile setting in the web.xml. See your servlet/jsp reference on what to do. |
| | |
| | Ditch JBuilder 3. There's no reason whatsoever to still use that dinosaur. |
| | start with a search engine to find out what you're expected to make... Try writing up some specs. THEN try to decide what technology to use to implement it. If there's still time after all that, try to implement it using that technology. |
| | no, we're NOT going to do your homework for you. And we're NOT going to open some Word document posted by someone who doesn't even bother to write proper English (or anyone we don't personally know for that matter). Guidance: do your own homework, don't go play until someone hopefully … |
| | Al Jazeera is indeed bad. They're called the Osama News Network for a reason... |
| | the best way to reduce CO2 emissions (which seems to be all the greenies are concerned about, showing just how shortsighted and illinformed they are) is to kill all those greenies (taking away all their emissions from breathing as well as all other activities) and use their ground up bodies … |
| | Re: HashTable Output don't use Hashtable, it's to be considered deprecated. And never call anything "enum" or "Enumeration" to avoid major trouble with modern compilers. If you want your data ordered, use a LinkedHashMap.  |
| | and now to hope you never get any phone number that's not a US number... |
| | if you failed to find it yourself with even minimal effort, you'd better give up right now and except that failing grade. Why go through the trouble of trying to cheat people into helping you cheat yourself into a passing grade (and that's the only thing you can hope to … |
| | no, we're not going to do that. We're certainly not going to sheepishly compile and run your code and fix it for you. |
| | try the C++ and Delphi manuals, which you will have if you have a legal version of the product. If you don't, you don't deserve any help. In fact you deserve only contempt if you use pirated software. |
 | $30 a month may pay for a single person for about half an hour (depending on how much they get paid, but if they're good they'll get decent pay...) And that's without covering for the cost of infrastructure, study material, etc. so you'd better consider that only about $10 goes … |

| | How to judge this depends on what your intentions were when writing it... As a means of adding 2 numbers it's overly complicated, as a way of learning how simple classes can be written it's not bad. |
 | Re: Java IDE(s) BlueJ is a disaster. It does NOT teach you programming, it teaches you some button clicking. If you want to learn the language, don't use any IDE but a text editor and command line. That way you'll learn the language rather than the tool (which is what way too many … |
 | WHAT exception? And where? And no, we're not going to download and execute some code you attach here or anywhere else. Such tricks are far too often used by people trying to spread virusses. Plus it's not our task to figure out what problems you're having, that's your job. When … |

| | use your own brain, if you're indeed a student at that level you're supposed to have one. |
 | place it in the correct location within your web application and it will be picked up automagically. that location is of course the WEB-INF/lib directory. |
| | [quote]I think avoiding a second pass over the string is a fantastic reason not to use it. Microseconds add up faster than you might expect.[/quote] Something every sane programmer'd do only once, he'd not call strlen for every iteration of the loop but once before entering the loop, saving the …  |
| | and what hardware architecture, what mouse (USB, PS/2, serial, something else maybe). I've done it 15 years or so ago. At the time we had to write our own mousedrivers, was fun. I think the disk with that code is by now unreadable (not that it would do much good … |
| | 1) figure out what Pascal's triangle is 2) learn a programming language 3) implement the thing in that programming language |
The End.
