What Is Wrong With Java? STILL NOT ANSWERED, PLEASE ANSWER!

Question

So today (10 PM January 20th), the Firefox Plugin Checker said that my Java version was outdated. I also got a pop-up saying that my current version of Java at the time (Java 7 update 10) had vulnerabilities. So to try and fix this, I went to the Java page and downloaded the update (Java 7 update 11).
To check and see if my update was working, I went to Java's check page, as well as another page I use. And here I discovered a problem. I got a notification that an old version of Java had been detected, and another prompt to download the current version (which I had already done). So I erased all versions of Java from my control panel, and tried to check it again. And when I did, I got this: http://oi50.tinypic.com/35b6xx2.jpg and http://oi47.tinypic.com/15fg37p.jpg.
As you can see, both pages tell me that I need to install a missing plugin of some sort. So, thinking this would resolve the issue, I clicked the Install Missing Plugin button. This is what it told me was missing: http://oi45.tinypic.com/302uwbl.jpg. So I clicked next to install it.... and got this: http://oi45.tinypic.com/2cici0x.jpg, which I assume means that the plugin did not install. So I pressed Manual Install... and was lead/linked right back to the Java download page (where it all began, and what doesn't seem to be working in the first place)
I go to check my plugins again (Just to make sure and also for extra information), and it appears to say that my Java version is current (is that what "Java Deployment Toolkit 7.0.110.21" is? I don't know, I am not good at technology at all. Either way, here is what it looks like: http://oi48.tinypic.com/4kxzz4.jpg). So...if it is current, why is it not working (i.e. I am unable to play games, DO MY COLLEGE CLASSWORK, or play Java-based games)?
If it helps anything, here is what my control panel looks like in regards to Java right now: http://oi45.tinypic.com/2qlxu9t.jpg Am I missing anything that would make Java work?
And before anyone says that Java is not essential: It may be that way to you, but I need Java to do classwork for college. Veterinary college.
So, in short, what is going on with Java, and how can I fix it?
EDITEDITEDIT: I Have found that I can do my classwork without Java.
HOWEVER, this DOES NOT mean that the problem is solved or over with. I STILL WANT TO KNOW HOW TO FIX THIS PROBLEM AND GET JAVA TO WORK. Even if I never actually need it, I would still like to have a (working!!!) Java version because of two reasons: 1) I would rather have such a program and not need it, than need such a program and not have it, and 2) aesthetics. Sorry to say, but I am very particular about how things look when it comes to my belongings, and the fact that Java is messing up is making me actually stressed. In short, I still want the above issue solved, even if it's just purely for the sake of Peace Of Mind.
