 | toString() gives you a string representation of your object. But you have to define that string representation if you want it to be anything meaningful and human readable. The default implementation just gives you a hashcode for the object in memory, useful to distinguish between 2 instances but no more. …  |
 | you've never seen one because making one in VB6 is the worst idea you could ever come across. Terrible security features, vulnerable to just about any hacking strategy known to man and then some, outdated and out of support before online banking even existed. Leave real programs to real professionals, …  |
| | Re: Playlist java do your own homework, kiddo. If you've specific detail questions people will be happy to help, but we're not here to help you cheat and get a passing grade on your course by doing your work for you.  |
| | > So many ... dead threads ... now ... being resuscitated? happens every new semester when programming courses start in certain countries where the majority of kids aren't interested in learning, only in getting the paperwork so they can get hired by firms that then sell them to other companies … |
| | I hope not. It's the only way to get rid of the flood of highly annoying adbanners with fake download buttons and redirects to phishing sites. |
| | I think he's trying to spam. All his posts are seemingly random phrases posted to seemingly random forums.  |
| | Re: Networking he probably means physical connections :) Can only plug in so many cables after all. And yes, you can plug in a switch or router into your DSL modem/router.  |
| | As a programmer, don't "study" operating systems, study programming paradigms. But if you're asking whether there's more money in programming for Windows or iOS, it all depends on what you're interested in selling. If you're into "hip" "apps" and games for teenagers and gadget addicts, Apple's your thing. All those …  |
| | even better, put it all inside a method and just call that in your loop. Much easier to read... |
| | do you really think some kid asking to get their homework done for them is going to come back years later and give you their homework they never got done in the first place because nobody did it for them? <insult snipped>, you don't deserve even a failing grade, you … |
| | Typically, you'd just have a method in the main class that does that stuff, or in a class where you launch it from the main class. A single entry in a properties file can then be used to determine whether that initialisation method runs or not. |
 | Android Studio is the fastest IDE around. You can of course do things the hard way and write all your code in a text editor like VI or Notepad and then use commandline compilers. Most likely if it's slow on your machine there's something else wrong with your machine. I'm … |
| | yeah, create an installation DVD or USB pen drive using the media creation tool. Then (or while doing that, it takes a while) save all your data and stuff you want to retain from the old PC to an external hard drive. When both are done, put in the installation … |

| | correct. The problem statetement merely tells to solve the problem, not how to solve it :) And for this kind of thing a spreadsheet is the easiest way to go, it's exactly what spreadsheets were designed to do... |
 | being able to do that would be (and was) a major security risk. If you can do it, so can a mallicious site... |
| | don't use executeUpdate for select statements, use executeQuery. executeUpdate will never result in a ResultSet. According to the javadoc for getResultSet: > returns the current result as a ResultSet object or null if the result is an update count or there are no more results |
| | post your problems here, don't just link us to some other site and expect us to work it out for you. |
 | yes, your reputation haunts you. Welcome to the real world. Just as there is no "lifetime hosting" unless your life is very short, so there is no "100% guaranteed" way to prevent black hats from getting into your systems. All you can do is make their life harder. And how … |

| | > Rule number 1 - don't let anyone do your thinking for you. including people who state rule number 1... That's the paradox, isn't it :) It's true though. Trust, but verify. If it sounds too good to be true it probably is. Carpe Diem Live like there is no … |

 | the MySQL syntax may be slightly different (my main experience is with Oracle) but this is how you'd do it in Oracle: `ALTER TABLE POSTS ADD CONSTRAINT POSTS_MEMBERS_FK FOREIGN KEY (MEMBER_ID) REFERENCES MEMBER(ID) ENABLE;  |
| | hmm, tbh I'd go a few rungs up the ladder and use something like JMS to handle most of the nitty gritty details for me...  |
| | if you look at what really happened, VW did nothing wrong. Some flunky broke a non-story as a major "evil corporations breaking the law with software to cheat" when that's not what happened at all. Bosch created the software which controls the engine performance tuning of VW diesel engines (and … |
 | it's indeed gotten way way harder to find anything specific. Not only do you have to scroll through all the dozens of collated pinned posts (while it may have been 2-3 per forum, if you combine 20 forums into 1 that leaves you with 40-60 of them), but there's no … |
 | That's an extremely broad topic... Without programming there's no software. Without algorithms there's no programming. Of course implementing an algorithm in a computer program requires programming. But you can envision an algorithm and describe it in other contexts as well, without writing any need at all. For example a sorting …  |
| | looks good, but without a menu it's going to be a nightmare to navigate. |
 | you NEVER debug production code. Rather you analyse the log files (those should of course exist and be designed to have useful information), then try to recreate the scenario on another machine (which should be as close to the production environment in all respects as you can get it, including … |
| | I'm all for condensing the signatures :) Doesn't mean mods can't be identified though. There's room next to the rep count (or is that rap sheet?), or use a different colour font for their names.  |
| | Re: programming open source does not mean no cost. There can certainly be a cost involved, but generally that cost will be no more than the cost of delivering the code to you (e.g. a company I used to work for had an open source project, the source would however be distributed … |
 | yes, add it to the WEB-INF/lib folder. That's the classpath for a web application, everything else is ignored except those classes provided implicitly by the application server (the JEE and standard libraries, and sometimes things in an ext lib directory as defined by the application server (which would be specific … |
| | Re: Problem Solving no need to draw anything out of the boxes. Just open them and look inside... Yes, that's a trick answer to a trick question. |
| | Re: Nested Loops? read your inner loop carefully. j starts at 1, then is decreased until it is smaller than i. i starts at 6, then is increased. So your inner loop never terminates, as it starts smaller than i, and then is made ever smaller and smaller. Of course eventually it will … |
| | Read your warranty carefully... Depending on brand and sometimes even product it can vary wildly. I KNOW Nikon USA for example does not honour any warranty for any Nikon product that's not sold by them, and the rest of the world does not honour warranty on anything sold by Nikon … |
| | WTH are you trying to submit a 30MB http request in one bit? Multipart mime requests have been with us for over a decade. |
| | Java does not give you direct memory access, that's one of the main reasons they designed the language in the first place, do away with all that messy malloc, calloc, etc. etc. you're stuck with in C. And no, your program doesn't allocate any memory at all. It requests storage … |
| | why should we help you leech data from other peoples' websites without their permission? Contact the site owners and ask them if they can supply you with the data. If the data is supposed to be available to other applications, they'll have a system in place you can subscribe to … |
| | Re: help with code you don't want to do any of that. https://crackstation.net/hashing-security.htm Do NOT try to store passwords unless you have to, and then only do it if you really know what you're doing (and if you're asking this, you don't). |
| | main observation here: don't do this. NEVER create SQL statements this way, ALWAYS use PreparedStatements or better yet JPA. Prevents a lot of problems. |
| | porting usually means getting something to work on a different operating system and/or hardware. This is largely a manual process (though I'm sure there are tools that can help identify common areas of interest). Transpiling is the move of one language to another. While there are tools that can help …  |
 | an instance of an inner class exists only within the context of an instance of its outer class, UNLESS it's static. Result is that an inner class of a non-serializable outer class is not serializable, even if it is marked as serializable itself. |
| | signatures are way too big and prominent. Tag clouds appearing only at the far bottom are a pain, place them in the side bar instead. |
| | Re: New design live Overall, very nicely done. Clean and modern, professional look. Some points though: 1. the white margins on the left and right are rather big, costing a lot of room on screen. Make the main pane wider, so people need to scroll less. 2. Font could be a tad smaller (1-2 … |
 | you NEVER, EVER want to store plain text passwords. It's an invitation to getting your users' accounts stolen, and most people use the same username and password in a lot of places... You also NEVER, EVER, want to use MD5 as it's not secure at all. https://crackstation.net/hashing-security.htm read this as …  |
| | never heard of thymeleaf, JSP is way outdated. Use JSF instead. Spring MVC of course doesn't force you into a specific view technology in the first place. Decoupling is the name of the game after all. |
 | Re: Scary webservice why scary? Any logout from any website is just a link you click. Which submits a request to a webserver somewhere. Javascript can submit requests to webservers, so can a lot of other things. Of course it's possible to write a logout system that requires active cooperation from the user, …  |
