  • What are the things Java got wrong?

    - by Alon
    I read a lot of blogs and see people all the time talking about bad things in the java programming language; a lot of them are about annotations and generics that were added to the language in 1.5 release. What are the things in the language or the API that you don't like or would design differently?

  • Some confusion with a class variable, but with a twist...

    - by Omega
    I have a class called MyPackage.WebServer and it has a property called DBEngine. I am also dynamically loading a module and class using load_module. Inside this class, it attempts to reference MyPackage.WebServer. When it does though, DBEngine is not set to the value given when WebServer is instantiated. It's the default (None). Would the fact that I'm using load_module cause a different object graph to be created and thus isolate my dynamically loaded class from the rest of my python app?

  • Set Date in a single line

    - by hibernate
    According to the java API, the constructor Date(year, month, day) is depreciated. I know that I can replace it with the following code: Calendar myCal = Calendar.getInstance(); myCal.set(Calendar.YEAR, theYear); myCal.set(Calendar.MONTH, theMonth); myCal.set(Calendar.DAY_OF_MONTH, theDay); Date theDate = myCal.getTime(); However, I would like something shorter to replace it with (ideally one-two lines). Any suggestions?

  • How can I close a JFrame by click on a button?

    - by Roman
    I would like to have a button in my window such that if I click it (button) the window is closed. I found out that I can close a window in the following way: referenceToTheFrame.hide(); //hides the frame from view refToTheFrame.dispose(); //disposes the frame from memory But if I do this way, compiler complains: Note: myProgram.java uses or overrides a deprecated API Note: Recompile with -Xlint:deprication for details. Do I do something unsafe?

    - by RHicke
    Currently I have a website on the Google App Engine written in Google's webapp framework. What I want to know is what are the benefits of converting my app to run with django? And what are the downsides? Also how did you guys code your GAE apps? Did you use webapp or django? Or did you go an entirely different route and use the Java api? Thanks

  • Null pointer exception on .iterator() call

    - by Peter
    I'm getting a strange NullPointerException, evidently thrown by the following line of code: Iterator<Note> it = notes.iterator(); I've checked, and at the time the java.util.TreeSet notes is always non-null (with 15 elements). The TreeSet API says nothing about iterator() throwing NullPointerExceptions. What else could be going here?

  • Using Message Boxes in Windows 7 style

    - by Meta
    After reading the MSDN article about proper user interface here: http://msdn.microsoft.com/en-us/library/aa974176.aspx I want to modify the message boxes I use in my applications to reflect those guidelines (for example, have the Main Instructions in a larger font, better named Buttons, etc...). My question is, is there an API that allows you to easily build those kind of message boxes (a la user32\MessageBox()), or do you actually have to build your own message boxes which follow the guidelines?

  • Prevent initial array from sorting

    - by George
    I have an array where the order of the objects is important for when I finally output the array in a document. However, I'm also sorting the array in a function to find the highest value. The problem is that I after I run the function to find the highest value, I can't get the original sort order of the array back. // html document var data = [75,300,150,500,200]; createGraph(data); // js document function createGraph(data) { var maxRange = getDataRange(data); // simpleEncode() = google encoding function for graph var dataSet = simpleEncode(data,maxRange); } function getDataRange(dataArray) { var num = dataArray.sort(sortNumber); return num[0]; } I've also tried setting data to dataA and dataB and using dataB in the getDataRange function and dataA in the simpleEncode function. Either way, data always end up being sorted from highest to lowest.
