23,295 | 2 | null | 22,697 | 11 | null | We are heavily using [EasyMock](http://easymock.org) and EasyMock Class Extension at work and are pretty happy with it. It basically gives you everything you need. Take a look at the documentation, there's a very nice example which shows you all the features of EasyMock.

23,308 | 2 | null | 18,533 | 3 | null | I've been using the [Data Transfer Objects](http://en.wikipedia.org/wiki/Data_Transfer_Object) pattern (originally from the Java world, I believe), with a SqDataReader to populate collections of DTOs from the data layer for use in other layers of the application.

23,316 | 2 | null | 23,310 | 0 | null | Well, if you are just wanting to learn on your own, I would say you should go with something free, like subversion. If you are a company who has never used source control before, then it really depends on your needs.

23,322 | 2 | null | 23,310 | 0 | null | My first exposure was CVS with WinCVS as a client. it was horrid. Next was Subversion, with TortoiseSVN and Eclipse's integration.

23,324 | 2 | null | 23,277 | 13 | null | To expand on Konrad's comment:

Because of this, functional code is generally easier to parallelize. Since there are (generally) no side effects of the functions, and they (gener... | null | CC BY-SA 2.5 | null | 2008-08-22T19:53:55.163 | 2008-08-22T19:53:55.163 | null | null | 1,409 | null |
23,321 | 2 | null | 23,310 | 8 | null | I'd suggest you try Subversion, for example with the [1-click SVN installer](http://svn1clicksetup.tigris.org/). Try searching SO for "Subversion", and you'll find loads of questions with answers that point to good tutorials.
Good luck!

23,335 | 2 | null | 23,277 | 26 | null | I believe that procedural/functional/objective programming are about how to approach a problem.
The first style would plan everything in to steps, and solves the problem by implementing one step (a procedure) at a time. On the other hand, functional programming would emphasize the divide-and-conquer approach, where t... | null | CC BY-SA 3.0 | null | 2008-08-22T19:57:34.877 | 2015-04-10T03:07:14.550 | 2015-04-10T03:07:14.550 | 541,136 | null | null |

23,333 | 2 | null | 23,287 | -5 | null | I think it would be good to store somewhere all possible primes smaller then n and just iterate through them to find the biggest divisior. You can get primes from [prime-numbers.org](http://www.prime-numbers.org/).
Of course I assume that your number isn't too big :)
