I'm completely at loss how the ant task ivy:publish is supposed to work. I would expect that I do my normal build, which creates a bunch of jar files, then I would push those jars to the (local) repository. How can I specify from where to retrieve the built jars, and how would those end up in the repository? Update: <target name="pub...

I am considering writing two limited precision alternatives to BigDecimal, namely DecimalInt and DecimalLong. These would be capable of dealing with numbers within the real bounds of int and long with an arbitrary number of decimal places, creatable in both mutable and immutable form. My plan is to make DecimalInt support +/-999,999,99...
So regular expressions seem to match on the longest possible match. For instance: public static void main(String[] args) { String s = "ClarkRalphKentGuyGreenGardnerClarkSupermanKent"; Pattern p = Pattern.compile("Clark.*Kent", Pattern.CASE_INSENSITIVE); Matcher myMatcher = p.matcher(s); int i = 1; while (myMatcher.find()) { Syst...
** Dup: http://stackoverflow.com/questions/226002/whats-the-difference-between-x-x-vs-x ** So, even though I know you would never actually do this in code, I'm still curious: public static void main(String[] args) { int index = 0; System.out.println(index); // 0 index++; System.out.println(index); // 1 index = i...
This pretty much has me defeated. On XP and earlier versions of Windows you could customise Open With filetypes to include java - jar "myjar.jar", but on Vista this functionality seems to have been removed. I can of course create a .bat file to launch my application, but is it possible to make Vista execute a .jar as required? ...

I am trying to process files one at a time that are stored over a network. Reading the files is fast due to buffering is not the issue. The problem I have is just listing the directories in a folder. I have at least 10k files per folder over many folders. Performance is super slow since File.list() returns an array instead of an iter...

How can I create a JButton in Swing with the icon above the text? ...
I have been working on a Java project for a class for a while now. It is an implementation of a linked list (here called AddressList, containing simple nodes called ListNode). The catch is that everything would have to be done with recursive algorithms. I was able to do everything fine sans one method: public AddressList reverse() L...
For example, I could write either of these: class example <T> { ... public void insert (T data) { ... } } or class example { ... public void insert (Object o) { ... } } Is there a signficant difference between the 2 in terms of performance? With generics I could restrict the type of...
