 | Re: NetBeans don't use the "drag and drop method". it generates hardly readable, even harder to maintain and very crappy code. you'll be in a lot of trouble trying to debug that. rewrite your classes in a way you understand them (do hope you seperated your GUI from your other layers). if …  |
 | never met him, so I won't start on whether he's "good" or "nice". sure had some talent as an actor, even though the Fast & Furious series he was most known for, aren't really the type of 'great acting' movies. liked him in Timeline, though.  |

| | well, this code looks very fishy to me: String[] t=new String[arr.size()]; t=arr.toArray(t); for(String j:t){ return t; } 1. declare your t array outside of the loop, don't create a new instance each iteration, just overwrite the existing one: String[] t; while ( condition ){ // ... t = new String[arr.size()]; … |
 | and change books/courses: if it has J2EE in the title, chances are high it is outdated, since J2EE became out of date early 2006, when it was replaced by Java EE 5 (and has been called Java EE x every since) Another good thing to realize: don't go for "shortest … |
| | why would you? installing the jre (if it's not installed by default, that is) is simple and it's free of cost. another way of doing so, would be: don't write your applications in a language that depend on a (J)VM to run it in. |
 | why exactly do you have that 'InteractiveCampaignManager' class? |
| | hosting is providing a server, with the necessary functionalities to support all your needs. hosting means you can upload your webapp/website on their server, and they'll maintain the actual server it runs on. might be you get a number of email addresses, might be you can have your own url, … |
 | if the goal is to "quickly gain reputation points", you're doing something wrong. the reputation a user gets is basically irrelevant. you should be here either to help learn, or to learn yourself. having a good rep is nice, but if you can't help out people without having the best … |
 | my post count dropped with (almost) 10, as for reputation points, I've lost about 500. must 've been some popular posts that got removed from the count :) |
| | what kind of content has been changed? if it's an image you linked to from another page, might just be the owner replaced the image. if it's part of the wordpress text, maybe there's been an update of their material. anyway, wordpress isn't the best way to create a website … |
 | not sure what to think of it, after all, it's a reply to a dead thread. but some advice: I would be careful with code like this: catch (FileNotFoundException fe) { } this is just hours of needles debugging waiting to happen. |
 | kind of doubt it. nowadays you need a google account to be able to get access to stuff that didn't use to require it. that also explains part of the increase in numbers. Google+ has it's pro's, no doubt about it, but it attracts a different type of user when … |
 | Diafol: whether you agree with it or not, JWenting has as much right to an opinion as you or I. I assume he's referring to a lot of people who adore Mandela and treat him as if he never made a mistake in his life, or walked the 'path of … |

 | ehm... you can use photoshop, paint shop pro, even paint, if you're good enough at it. |
| | ehm... this is not something you can do just "code based". most likely you'll need some costly hardware to go with it, and you can make the service "free", but it's likely you'll still have to pay for it. |
 | well, if you write it to be a standalone app, why wouldn't it be possible offline? but , that would bring in the disadvantage that only on your local pc the data can be updated, and it can not work with online resources. of course you could also have a … |

| | and you assume America hasn't got access to Facebook/Twitter/Google? |
| | that is because a primitive can not be null. null is when you have an Object that is not yet instantiated. you'll need to verify first whether or not you have null there, before trying to parse it to an int, and provide a default value or throw an Exception. |
 | pelle12: then again, why would anyone run a native Windows executable on Linux? |

| | chances are pretty good it's a jquery plugin. by taking a look at the source code of that page, these might be a good place to start your research on: <link rel="stylesheet" type="text/css" href="ddsmoothmenu.css" /> <script type="text/javascript" src="js/jquery-1.6.4.min.js"></script> <script type="text/javascript" src="js/jquery.mousewheel.js"></script> <script type="text/javascript" src="js/jquery.jscrollpane.min.js"></script> <script type="text/javascript" src="ddsmoothmenu.js"></script> |
| | Re: Java questions never worked with jsf or portlets, so I'll leave it to that, you're definitely wrong in your last answer, though. 'Can I restart a completed thread?' No, you can't. what you can do is start a new one of the same type, just not the completed one. that one's gone. |

 | Re: Reverse Number a "quick fix" to reverse a value, is to turn it into a String, and reverse it's characters. after that, parse it back to a double. you'll save yourself quite some logic/work.  |

| | since we have no idea what LoginDao.validate(obj); does, how it validates, or what it returns, there isn't much we can help you with. one good advice though, learn how to use servlets. putting actual Java code in your jsp files is very bad design. |

| | a few remarks. a few small refactorings, to make your code in less lines, and more readable. `if ( btnOne.isSelected() == true )` this is actually the exact same as: `if ( btnOne.isSelected() )` and it's better to use an if-else statement, rather than two ifs. that way, your value …  |
