Hello, Is it possible to use a Comparator without implementing the Comparable class? For instance, if I had the following: MyClass { Comparator comp; OrderedListInheritance(Comparator c) { this.comp = c; } } Could I then use comp to compare two objects? If so, how would I go about doing that? Thanks... ...
Hey guys, I was messing around with C/C++ and recently found the _getch() function. I also recently got an invite to Google Wave (amazing, btw), and I wanted to emulate the ability to send messages before you actually hit the enter key. However, I don't know much (anything <.<) about networking in C/C++, while I know a decent amount abo...
I am currently working on some Java code that has a lot of ActionListeners defined in it (one for each JButton) and there are around 60 buttons. These are all defined as anonymous inner classes in the JButton.addActionListener method. I have been thinking of ways to refactor this to make the code look neater as this is making it looked v...
Okay I understand this might be a simple question, but I was trying to figure out how to make a JAR file so that other people can run my program without having a software like jGrasp, eclipse, or netbeans. The problem I'm having is I save it as a JAR file and can execute it on my computer but when I email it to my friend, it says invalid...

I'd like to read some data from an NFS share from my Java program. I'd need the program to authenticate to the NFS server first, then do the I/O. (Requiring the NFS share to be previously mounted is not acceptable.) So, I'd like the functionality that's provided by this library: http://jcifs.samba.org/ , except for NFS instead of CIFS....

I can perfectly see why Clojure is really good for concurrent programming. I can see the advantages of FP also in this regard. But clearly, not every line of code that we write is part of a thread or needs concurrent access. For those parts of the code (the more simple and sequential piece of code) what is it that Java really missed tha...
I'm trying to convert from HTML to Latex, and want to change this: <a href="www.foo.com/bar">baz</a> into: baz\footnote{www.foo.com/bar} I'd like to generate a Clojure function to take a chunk of text, and replace as many matches as exist in a given paragraph. I've tried (.replaceAll "<a href=\"foo.com\">baz</a>" "<a.*h...

I'm using JODConverter 3.0 to handle communicating with OpenOffice to convert documents. Everything is working fine except that JODConverter uses a Java library from OpenOffice that uses JNI to grab certain library files from the system. This throws an exception if I don't set the java.library.path method using -D when running java. The...

My problem is to generate version 1 UUIDs. We use Jetty 6.x, Maven (to start Jetty among other things) and Apache Commons ID (to generate UUID version 1 from the current time). Apache Commons ID requires a configuration file that is told to the JVM, using a parameter, e.g. 'org.apache.commons.id.uuid.config.resource.filename=commons-id-...
