What is Java and why do I need it?
Java is on my computer and it thinks it's important, so it informs me that it needs updating periodically.
I don't click the link in the notice, though, instead going to Programs and Features and accessing the link there. It checks my computer and tells me, yes you need to update, and I do it.
But whenever I'm on Facebook, I get a message from FB that it needs to run the Java Runtime Environment Update XXX.
If Ive already installed the update, shouldn't it be running already?
Has anyone else seen this when on FB?

I do not think FB should ask that if you have already updated. It could be a malware attack but this is just guessing. I only use FB with my phone but I think Java is not needed. I tried to find the software requirements but didn't find that place. Java is normally not needed and I suggest people to uninstall it unless they need it because it is a common attack route.

Java is an application that lets web designers impress themselves by writing code that runs on your machine to accomplish things that could almost always be done better and more easily in other ways.
 In order, then, to discover the limit of deepest tones, it is necessary not only to produce very violent agitations in the air but to give these the form of simple pendular vibrations. - Hermann von Helmholtz, predicting the role of the electric bassist in 1877.

Thanks, slart, that bit about some education software requiring Java reminded me that I downloaded it for my landlady's grand-daughter who was using my computer for her school work.
It's now on the hit list.

Yeah, we use Javascript in our php customer web portal and I blow hot and cold on how we use it. If I had my way I'd kill it but we have three or four pages that would require weeks (if not months) to re-write and test. That's time we don't have. The only thing I impress myself with it is I can actually make it work about 50% or the time.

Um, Java is not Javascript. "Real" websites don't need Java, but many rely heavily on Javascript. Here's one of several websites that detail the differences: http://www.htmlgoodies.com/beyond/javascript/article.php/3470971/Java-vs-JavaScript.htm

I used to play chess & bridge online on Yahoo games (until they discontinued it) and they both used a Java app......other than that, I'm not sure why I'd need it now (even if 3 billion devices run on Java).
I'm not sure if Steam or Origin needs it as those are my gaming platforms.........I probably should just uninstall Java.

I need Java everyday or I get really crabby. I get headaches, stumble aimlessly down hallways, and wonder how to make the day stop spinning. I see someone in the break room guzzling a mug of coffee and I focus on their jugular. It pulses with fresh, hot caffeine. With a quick bite, just a little one, I could tap into that...
Oh, you weren't talking about the hot beverage. Never mind.

Java and javascript are two totally different beasts. Java is an object oriented language that is painfully slow but theoretically easier to learn than languages like C. Javascript is scripting language used by most websites to some degree. It is a lot harder to avoid and many sites will not function without it. As the article slartarbartfast shared, the most prominent apps to use it are a few online games and Open Office. I sometimes consider tossing Open Office for that reason since i use Java for noting else.

The "painfully slow" quality was once true but has not been a valid criticism for over ten years now. Yes, optimized C can run marginally faster, but Java in a modern Java Virtual Machine runs like a bat. Java is not "theoretically" easier to learn than C. It is unquestionably easier to learn. It also is far more efficient in the pursuit of producing working, bug-free code due to the compiler's enforcement of type safety, the lack of a pointer data type, and a considerably more elegant object model. Sadly (for us Java enthusiasts anyway) the language is of little or no use in musical applications. C/C++ rules in this area and probably always will for the foreseeable future. Too bad, since Java has a killer set of classes for working with MIDI data and files.

Then again if Sonar was made with Java it would force people to have 'dangerous' software needed to run Java apps, right?

I never clicked the 'allow' button on the message.
I deleted Java from the computer and now when I go to FB I get this message:
"this webpage wants to run the following add-on: 'control name is not available' from 'not available' ". I don't click that 'allow' button, either.
Definitely something fishy going on.
I mean besides facebook.

I just take screen shots of those errors and forward them to the NSA. I mean, they're watching all of this anyway, so they must have some idea what's going on. Oh, just a minute. There's someone at the door. They're really insistent.

Sounds fishy indeed. You could run Malwarebytes or HitmanPro or something similar just in case your computer has been compromised. Even better thing to do could be to restore your Windows to an earlier state that hopefully is malware free. Or you could try another browser to find out if the same happens. And you could take a look and see if there is some fishy browser plugins lurking in your browser.

You could also try typing the FB address manually instead of clicking on a bookmark and you could also check the bookmark if there is something wrong with it(all assuming you actually use bookmarks).

But whenever I'm on Facebook, I get a message from FB that it needs to run the Java Runtime Environment Update XXX.
If Ive already installed the update, shouldn't it be running already?
Has anyone else seen this when on FB?
This particular message seems to be asking permission to run the already installed Java Runtime Environment. If Java is installed on your computer, there are settings in the "Java Control Panel" (Configure Java) that allow you to permit it to run on your browser at all, and to run with various "security levels." If the site cannot work because of this kind of security issue, then you need to enable a less secure interaction if you want it to do what the site intends. When the Java security fiasco began, there were all kinds of articles advising to disable browser access or set security levels to high. In fact one of the first security "patches" released was just an automated setting of the security level to high. A series of patches followed that seemed not to fix the problem or not to fix new problems that kept cropping up. No one really trusts Java anymore, so most recommendations now are to just get it off the machine unless you really need to use it for something. Definitely if you are going to use it you want to keep it updated.
