• Overload with different return type in java?

  - by nunos

  So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java? By the way, just for reference, is this possible in C++? Thanks.

• popularity of C# vs c++, java

  - by every_answer_gets_a_point

  i dont understand why c# is so popular. if it's only good on windows, where as c++ and java work on any system, why is it that c# is so popular? is it because it's accessible to more people since it's easier to use? c# is the top tag in stackoverflow btw.

• Will there be any conflict with other applications when my application saves data in [NSUserDefaults

  - by bobo

  After reading this thread: http://stackoverflow.com/questions/2792932/nsuserdefaults-not-present-on-first-run-on-simulator I know it's quite easy to store some app data in the [NSUserDefaults standardUserDefaults]. But if other applications also happen to use the same key to store their data, is this possible that my app data gets overwritten? Many thanks to you all.

• Accessing JAR resources

  - by Pablo Fernandez

  I have a jar file with resources (mainly configuration for caches, logging, etc) that I want to distribute. I'm having a problem with the relative paths for those resources, so I did what I've found in another stackoverflow question, which said that this was a valid way: ClassInTheSamePackageOfTheResource.class.getResourceAsStream('resource.xml'); Sadly this does not work. Any ideas? Thanks! PS: Obviously I cannot use absolute paths, and I'd like to avoid environment variables if possible

• Generate 3 random number that sum to 1 in R

  - by user1034797

  I am hoping to create 3 (non-negative) quasi-random numbers that sum to one, and repeat over and over. Basically I am trying to partition something into three random parts over many trials. While I am aware of a= runif(3,0,1) I was thinking that I could use 1-a as the max in the next run if, but it seems messy. But these of course don't sum to one. Any thoughts, oh wise stackoverflow-ers?
