The goal is that a Java app provides contextual menu functions for files as seen in the Finder, thru the Services menu, on OS X 10.6 (Snow Leopard). Is that possible from within Java code, or do I need to write a stub in ObjC which then talks to the Java app (via a socket)? Any sample code around? ...
Hello! I was just wondering what a ghost reference was? Is it that you don't have to refer to a object? EDIT: Sorry, I wasn't clear, the langauge is Java, and I read it about linked lists. While reading a problem to write a LinkedQueue iterator to support the remove method. Then, you would have a ghost reference. ...
I have several different processes within a single project that I work on. I am constantly opening and closing tabs(java files) in the code editor for that particular process.

Yes, it's a trivial piece of code to write, but I still wonder if there's a built-in replacement. Here's the code: /** * Cast x to int, throw an exception if there's loss of information */ public static int safeLongToInt(long x) { int result = (int) x; if (result != x) throw new RuntimeException("long doesn't fit in an int: "...

I have two sets of Animal objects. The distance between animals is defined using a specific algorithm that looks at their traits. I am trying to design a method to find the pair from the two sets (one from each) that minimizes the distance. One idea I had: create a parametrized Tuple class to pair up Animals. Create a PriorityQueue with...

Hi all, I decided to create a currency converter in Java, and have it so that it would pull the conversion values out of a text file (to allow for easy editability since these values are constantly changing). I did manage to do it by using the Scanner class and putting all the values into an ArrayList. Now I'm wondering if there is a w...
I have data that is organized in kind of a "key-key" format, rather than "key-value". It's like a HashMap, but I will need O(1) lookup in both directions. Is there a name for this type of data structure, and is anything like this included in Java's standard libraries? (or maybe Apache Commons?) I could write my own class that basicall...
