Are there any professional Java desktop applications in use? I'm asking this because I started to study Java and would like to know it's possibilities and/or domains in which java is used.
Some of the largest existing ones are from the software development space (thats also the primary domain for desktop applications) like Eclipse or Netbeans or Rational Software architect.
Another big one is the IBM DB2 Tools (not the database itself). (But if you want to see something as a reference better not take these because they are slow as hell).

http://argouml.tigris.org/
http://www.magicdraw.com
http://www.jetbrains.com/idea
check out this SO question..its answers contain a list of desktop applications running on java.

DumpHD is a well-written application in Java; it works perfectly in Windows and Linux.
It's worth noting that both Eclipse and Netbeans also offer a platform for developing applications on and not just an IDE.
Here is a sample of applications written using the Netbeans Platform

I'm writing an application in java. In order to work my code properly, I want to check whether several software are installed. (This should be done in the java code itself.)
How can I do that?
This is a Linux system.
There are similar questions, but not exactly what I want.
Check if a program is installed on a linux machine from a java applet
There is no universal way of doing it.
You can use one of following approaches
Use java bindings for particular package manager for your platform if they exist.
Use one of the system tools like locate, whereis, etc. (which you didn't like)
Implement your own installed package detection, according to your requirements

Is there a way I can create an automated regression test suite in Java for IBM Mainframe applications? Preferably open source. I found some frameworks and tools, but the problem is most are either not in Java or are very expensive to license.
Some I found are:
Jagacy Jameleon plug in
IBM Rational Functional Tester
MF-Test
CA-Verify
HostExplorer
If you are testing applications in CICS it should be possible to run the JUnit framework in the WebSphere Liberty Profile available since CICS TS V5.1 (see https://www-01.ibm.com/support/knowledgecenter/#!/SSGMCP_5.2.0/com.ibm.cics.ts.java.doc/topics/liberty_overview.html?cp=SSGMCP_5.2.0%2F5-3-2). The test cases could use the JCICS API including LINK to call applications written in COBOL and other supported languages. Of course there are also a variety of production offerings too including Rational Integration Tester (Green Hat).

There are certainlý 3270 terminal emulators written in Java. Java can support CORBA and other older/business protocols. "If it happens, it must be possible." So the answer to your question as asked is "almost certainly yes".
Can't advise on tools without knowing exactly what you're doing. And tool recommendations are usually ruled out of bounds here as too opinion-based.
Define the problem better, and that will help you research what's available.

I was wondering which was more preferable for a VoIP Application that runs on Windows, Mac OS X, and Linux. Java or C++ and Qt?
I know Java runs inside the JVM and is limited due to that which means it can't communicate with the hardware directly which might be a downfall. But in your opinion which seems for plausible to use for such an application. ( eg. Jitsi using java or Skype with Qt )
Both are capable languages that are widely used for commercial application development. neither Java nor C++ is inherently a more suitable language for the sort of application you've described.
I personally prefer Qt for application development because I am more comfortable with C++ and in my experience, it is easier to develop attractive applications using Qt and C++ than it is to do the same using Java and Swing, SWT, AWT, or GWT.

I recently downloaded Java JDK, and installed it on my PC, yet I only received Java Mission Control, which is useless to me. Is there another way of getting programs to create apps in Java with?
Thanks :)
Personally I have used 3 different IDEs them being:
IntelliJ
Netbeans
Eclipse
I personally, as being the first IDE that I used was Eclipse, but Netbeans is taking a great liking on me because of its ability to use multiple different languages in an easy to use interface. Although Eclipse being the greatest in my opinion because of its easy keybindings and a ton of useful plugins. IntelliJ is the least favourite of the 3 because I find it cumbersome, but that is just my opinion.
I would do a quick google search for "Eclipse IDE", it makes the process of developing a program much easier in my opinion. It may seem intimidating at first but just look up a few tutorials and you should be okay.
find for
`
eclips
netbeans
IDE but these IDE are for professionals who are hands on java
after some set of practice's use one of above IDE
if you want to remember and learn the concept of .class files, packages and command line then go with
Notepad
Notepad++

Are there really any tools out there or sdk's that truly support cross-platform java mobile development, and are worth their weight in code?
I would like to rewrite our mobile application with an sdk that would allow usage on IOS (Ipad and Iphone), Android, and Windows Mobile 5 and 6.
If I am asking for the moon, please let me know.
I am traditionally a c# developer, and just moving into learning Java.
I see many different posts about cross-platform development but I wonder where we are as an industry today on this.
You could take a look to the mgwt or the codenameone framework.
For a server-based app built in pure Java but deployed via pure HTML+CSS+JavaScript: Vaadin. But that means your app requires an Internet connection to run.
Tip: Some folks build a bare-bones minimal native app that simply points a web-browser view directly to your site's URL. This allows you to sell/give your "app" in the App Store while actually building a web app that runs cross-platform.
There is no Java present on iOS. So there is no Java-based development kit to build local native apps across iOS, Android, and Windows Mobile.
Google did announce the J2ObjC project to translate Java code to Objective-C for the iOS. But that does not solve all your problems.
Eclipse Tabris is another option but it isn't free (It isn't costly either).
