Evening, kiddiwinks.
Essentially, this thread will be taking the same form as the one that Phil B. (I think it was Phil B, anyways) started some time ago on the Murga Forum. Anybody who's come across, or has regularly used, any specific Java apps that you think the rest of us may find useful, feel free to post about 'em.
These things often turn up in the most unlikely places.....or a well-known or complex app, which you might expect to be released in a standard package format, turns out to be written in Java.
I'm going to share a few; I know this first one is one Phil definitely dug up:-
It's kind of a Java version of what Google or Bing Maps offer, using the OpenMaps API/ecosystem. Works pretty well, too. Comes as a .pet.
----------------------------------
Next one is JDiskReport. It's a wee disk-usage analysis tool. 'Nuff said. This is an SFS.
----------------------------------
Next up is PinEmUp! - a Java-based 'sticky-notes' application, so's you can plaster reminders to yourself all over your desktop.... Pet package.
---------------------------------
This next one, um.....well; it very definitely functions, though I haven't as yet, quite got the hang of it. ScreenStudio is, as far as I can make out, a Java-powered version of OBS - Outside Broadcast Studio - but I haven't yet got the hang of the latter, either, so that's not saying much! 
Worth a look, perhaps, if you're wanting to make up your own vids from various sources...
--------------------------------
Then we have JPDFView. No prizes for guessing what THIS does. It's neat, practical, workmanlike; it gets the job done. Comes as a .pet package.
---------------------------------
Solo Java MP3 player is ALSO self-explanatory. Please note, when it says MP3 player, it means exactly that.........it will ONLY play mp3s, and doesn't function with any other format. Mind you, I've come across a few Linux apps of various types that are also dedicated to one specific format.... Again, a .pet package.
---------------------------------
This last one's just a bit of fun, really, though it IS fully functional. Who remembers the old-style adding machines we used to use in offices? Pull the handle for each operation, and it printed-out on a roll of paper tape? Then we got large, desktop-sized calculators.....though these still retained the paper tape printout.
Well, SuperbCalc is exactly like the latter. A large calculator, with "paper-tape" printout.....which can be detached, and saved/copy-pasted/whatever you want to do with it. You can change display/GUI size/colour, and it even has sound effects! 
Comes as a .pet.
--------------------------------
I've also got a number of individual .jar files. There's another music player; a basic notepad; a Java-powered installer for Capa Chess, a pretty nifty 3D chess game, itself Java-powered.....and what appears something rather like Google Maps, only laid out in Mercator projection, and apparently for mature students/university post-grads who are studying Geology..? Can't remember where I got this from, now.....it's around 60 MB in size, and for a Java-powered app is highly-detailed and pretty complex......called GeoMapApp.
I vaguely recall it was developed jointly between a British university, a Danish one, and a couple of American ones..?? (*shrug*)

Anybody else have anything you fancy sharing? Feel free to dive-in...!! 
If anyone has any links for sources of Java apps, those would be especially welcome.....
