How to change file extension at runtime in Java
Create instance of generic type in Java? Is it possible to create an instance of a generic type in Java? I'm thinking based on what I've seen that the answer is no (due to type erasure), but I'd be interested if anyone can see something I'm missing:  class SomeContainer&lt;E&gt; {     E createContents()     {         return what???     } }   EDIT: It turns out that  could be used to resolve my issue, but it requires a lot of reflection-based code, as some of the answers below have indicated.  I'll leave this open for a little while to see if anyone comes up with anything dramatically different than Ian Robertson's . How can I convert JPG into PDF easily? Is there any way to batch convert .jpg files into single .pdf files? How do electrons know which path to take in a circuit? The current is maximum through those segments of a circuit that offer the least resistance. But how do electrons know beforehand that which path will resist their drift the least? Can I update an early Airport Time Capsule? I have an Apple Time Capsule model A1254. It has a 1Tb drive. Is it possible to replace the drive with a larger capacity unit? It seems a shame to replace the whole unit. Thanks How to use z-index in svg elements? Unable to modify files/folders in NTFS partition Choosing GeoCoding service? I'm looking for a web service providing a full address based on coordinates (and reverse).  I'm ready to pay for that service.  I don't want to use Google's API. How do I sort a vector of pairs based on the second element of the pair? If I have a vector of pairs: std::vector&lt;std::pair&lt;int, int&gt; &gt; vec;  Is there and easy way to sort the list in increasing order based on the second element of the pair? I know I can write a little function object that will do the work, but is there a way to use existing parts of the STL and std::less to do the work directly? EDIT:  I understand that I can write a separate function or class to pass to the third argument to sort.  The question is whether or not I can build it out of standard stuff.  I'd really something that looks like: std::sort(vec.begin(), vec.end(), std::something_magic&lt;int, int, std::less&gt;()); Why won't this command work? /summon Villager ~ ~2 ~ {Offers:{Recipes:[{buy:{id:371,Count:15},sell:{id:264,Count:4}}   I'm using this as a recycler villager, and I can't get the first trade to work. What's going on? What is Ambient Occlusion? What is Ambient Occlusion and what are some of it's uses? I see it is used in creating what might be called "shadow catchers" in the following node tree setup: Does Devil's Fruit power gained depend on how much of it is eaten? Luffy accidentally ate the Gomu-Gomu (Rubber-Rubber) fruit, but was interrupted by Shanks after a few bites. It was too late and Luffy got the Devil's Fruit powers anyway. If he had instead eaten the whole of it, would he have got even more power from the fruit? Essentially as the title suggests - in some commutative ring $K$ (with 0,1), if we have 2 distinct proper prime ideals $\mathfrak{p}_1 \neq \mathfrak{p}_2$, is it necessarily the case (or if not, when is it the case?) that $\mathfrak{p}_1 + \mathfrak{p}_2 = K$ ?  I ask because I'm working through some lecture notes which frequently take some $K$ complete with respect to a discrete valuation, a prime ideal in a valuation ring  $\mathfrak{p} \subset \mathcal{O}_K$, a finite extension $L/K$, and then use the fact $\mathfrak{p}\mathcal{O}_L$ factors uniquely as some $\mathcal{P}_1^{a_1} \ldots \mathcal{P}_r^{a_r}$ (where $\mathcal{O}_L$ is the integral closure of $\mathcal{O}_K$ in $L$). Then we say $\mathcal{P}_i + \mathcal{P}_j = \mathcal{O}_L$ $(\forall$ $ i \neq j)$.   However it isn't clear to me, because we've made so many different assumptions along the way, what the reason is that $\mathcal{P}_i + \mathcal{P}_j = \mathcal{O}_L$. Is it because these primes occur in the factorisation of $\mathfrak{p}$, is it because of some property of Dedekind domains or fields, or is it not really possible to say out of context? Many thanks, and if anything needs clarification please ask. How can we know that all of the results for entangled photons are not chosen when the pair is created? Setup IIS 7.5 with multiple website bindings and SSL? On IIS 7.5 I am trying to achieve this with two websites:  Default Web Site is bound to:  (blank host header port 80 - http) (blank host header port 443 - https) go.example.com www71.example.com the IP address of go.example.com  2nd web site "Beta" is bound to:  beta.example.com (blank host header port 443 - https) * using blank only because it doesn't seem to be possible to    bind https to a named host header   And both need to work with SSL.  But I have these problems:   When I type in beta.example.com, I see the go.example.com site instead I can not seem to add the SSL binding to both websites at once (I have a single *.example.com wildcard certificate).  The beta site will not even start if I add the https binding to it.   This is how I have set it up:    What is the correct way to set it up? Long story short: since custom flag responses are messages to users like any other (answer, comment, suggested edit, chat message etc.), users should be notified about them!!    A problem I have with flagging, as it currently functions, is that flaggers are not notified about custom responses to flags, when they are given. I really don't care if I don't find out about every last flag of mine, whether it was marked "helpful" or not, but if a moderator went to the effort of typing out a custom response to my flag, explaining why it was or was not helpful, I'd like to see that response. The logical place for this response would be in the messages inbox (the red number thingy in the top left corner), where other responses to user actions (like answers, comments, edits, and chat messages) go.  This may also help to alleviate  of users not realizing that their flags go somewhere -- while I agree with her that "We shouldn't send notifications for [all] flag responses; that would be way too noisy for a lot of people," I think that in the event of a custom response, the flagger should be notified (because some mod thought that this information was relevant to the flagger), and it would not be too noisy because (in my experience1) most flags do not receive a custom response. This could provide one way that flaggers can be made aware of their flagging history.2    1 I don't know who can see this, but  on Mi Yodeya, to date, is 55 flags total (49 helpful), and only one custom response (....that I didn't see for a while, till I checked my flagging history for a different reason).  2 While I don't think that this will replace Monica's suggestion entirely, it would certainly help it a little.    To give credit where credit is due, while I came up with this idea myself, I did notice that someone else had posted about a similar idea earlier in a .  Edit: Just spotted  from the related questions along the side of the page; note that while that proposal is similar to this one, it was about sending all declined flags to the inbox, while I suggested that only the ones with custom responses should make it to the inbox. Is it possible to prevent LUDecomposition from pivoting? I was wondering about the reason of the choose of the X as symbol used to represents the "Close application" operation. Functions which are Continuous, but not Bicontinuous What are some examples of functions which are continuous, but whose inverse is not continuous?  nb: I changed the question after a few comments, so some of the below no longer make sense. Sorry. How does extra damage work for critical hits? What are acceptable reasons for flagging as "Requires Moderator attention"? After reading , I feel I don't quite understand this function. What are the guidelines for flagging a question as &quot;Requires Moderator attention&quot;?
