if I have a native android app (written in Java of course), what cross platform tool would you recommend to make it usable on iOS as well? I have been reading quite a lot about it, but most toold require code being written in html,css,js (phonegap, appcelerator etc), or for instance c# (xamarin), but which one would wrap my java code?

There is no solution that will work out of the box. You'll likely have to rewrite at least the UI whatever way you choose.
If you want the code to run on any mobile platform, you'll have to rewrite your code in html/css/js.
If you just want it to run on iOS, you have these options:
If you actually want to use the very same code, use RoboVM. This will allow you to parts of the original Java code on iOS in a JVM.
Another approach would be to automatically generate Objective C code from your Java code. This can be done using J2ObjC.

I want to develop for iPhone. I have only a little experience with programming in general. I am tossing up between Java on Eclipse with LibGDX OR Swift on Xcode. I have developer accounts so don't worry about that. Any suggestions?
If you want to develop only for iPhone/Mac, use Swift (or/and Objective-C) and Xcode. Everything will be smoother and Apps will be native. Keep in mind, though, that Swift/Xcode 6 are still in Beta, so you may encounter some difficulties if you want to ship your apps immediately. Apple should release the first stable version of Xcode with Swift before the end of the year, though, so you will need only a little bit of patience.
If you want your applications to be available in non-Apple platforms, then maybe go with Java, etc.
Side note: There is the chance that Apple makes Swift open, so developing with Swift for non-Apple platforms would be potentially possible... But I wouldn't count on it, though, at least for the near future.

I'm looking for a IDE that supports java and is based over terminal. I'm using Ubuntu 12.04 and it doesn't have any gui installed and I'd prefer to keep it that way. However, I'd also like to code on it and connect to it from other computers using SSH to code on there to provide a lightweight and fast IDE.
It has to be able to edit, compile, and test Java on the spot, and more languages if possible.
It would be nice if it had support for multiple projects and had a collapsible project browser, like in netbeans and most IDE's.
Does anyone know anything that meets the requirements?
I'd love something like http://www.spartacusrex.com/terminalide-1280x800.jpg however thats only for android.
emacs with JDEE is the only example I can think of. You might be able to get along with vim, but there will be a lot of ESC :! shell calls.

Which java framework is best for making of simulation of TCP's congestion control mechanism. I have started working with java Applets now But some articles on net makes me confused because they say java applets and awt are outdated.
The purpose of Applets is that they run in a browser. They have become largely unpopular, due to requiring the Java plugin installed & many security problems with same.
People have been widely recommended to disable Java plugins to prevent malware exploits using applet/ Java web start technology, so you will find it difficult to get people to see/ or run any applet you did make.
If you want to make a GUI/ graphical program, use Swing (or conceivably JavaFX) rather than AWT. AWT is grossly outdated.
Unless you really need your simulation to run in a browser, just make it a proper standalone application.

we are going to make an online classified ad for our thesis and we are going to implement some image comparison to filter out images that are inappropriate. http://www.ipol.im/pub/art/2011/my-asift/
based on this demo, ASIFT can match more keypoints than SIFT. how do u suppose we should implement this? should we use java? or can we just stick to php?
php is slow, its not a compiled language like Java or C++ (the source the website you quoted used) PHP is written in C though so the function could be compiled in without too much difficultly.
I would suggest a better solution would be putting the images in a folder and then processing with C++ or C directly and moving them to a "safe" folder which PHP reads from and displays.
http://dannagle.com/2011/09/benchmarking-c-versus-java-versus-php-programming-languages/
not a "full" test but as an example of the speed difference.
It is entirtely possible though to implement it in PHP, Speed would be a huge issue though

I want to create a simple desktop admin application for an IOS app that will work with a REST api I've built.
Couple of years ago I would go with Flex/Air, just makes it very simple. But since I am butt-hurt with the way Adobe have handled Flash in general, I am looking to write it using some different tool.
So far, Java Swing looks rubbish (UI-wise I mean). Others aren't cross platform and often too complicated.
Any suggestion?
Have you heard of JavaFx
http://javafx.com/
Check it out, it is cross platform and a good UI framework for RIA
