    Applets for online services, such as logins, FTP, and those kind of things. There are also Java applications that are used internally within software companies, though I don't see many of these making it to the outside world.

    Why is java so widely used?
    It's one of few multiplatform languages that can handle online execution or be executed locally (Applets & Applications). The libraries are quick and easy to install for the end user and it's mostly bug free. My $0.02 on security though: it's not very secure, because it runs on a VM. When C++ is compiled it's converted to bytecode (decompiled as assembly), whereas Java runs through the Virtual Machine and can (with a bit of work) be decompiled by the user. However, it's more secure than something like Python, where you have to distribute the source whenever publishing a project.

    What features of java make it popular?
    Popular to learn or popular to use? It's a great way for prospective programmers to learn to use a programming language, as it's easy to test (compiling is quick and easy and in some IDEs not even necessary), errors are pretty simple to decode, and it's not a time consuming process to use incremental programming.

    thank you guys for your info so far, can i narrow this down and ask another question?

    the reasons why java is used, and the features of java, i am able to find alot of info on.

    what is harder to find is where java is used. i know "everywhere" but like specific things....

    so i guess the question is how is it used in:

    Production
    Customer Service
    Gaming
    Mobile Devices

    thanks again guys. i have been googling for days, and able to find tons of features and benefits of java, but less able to find specifically the areas java is deployed.

    I can give a bit of an answer in relation to its usage in gaming:

    One of the largest MMORPG games ever, Runescape, is written as a Java applet. At least one other, smaller RPG, Puzzle Pirates, is written in Java as an easily downloaded client that self-installs. There are also several smaller games written by Jagex (Runescape) and Three Rings (Puzzle Pirates) that run as applets or Web Start/Self-installing apps. However, I have yet to come across a commercial java game that is in any way similar to the ones written in non-interpreted languages.

    So, Java is used mostly for applets/clients for games. After all, that's what it was designed for. Java also seems to be used for RPG games that don't have the kind of constant computation/rendering used in other types of games. That may just be the internet-based nature of the games it is used for, however.
    If the above doesn't make sense to you, ignore it, but remember it - might be useful!
    And if you just randomly taught yourself to program, well... you're just like me!

    In one of my latest projects I used Java in a kidney dialysis monitoring tool; I wrote a bit about it here. It was a hell of a project.

    kind regards,
