I just updated my java through the App store and when I typed "java" into spotlight, I got "Java VisualVM" without an icon so I clicked on it and it appeared in dock and then disappeared. What is this? Do I need it? How do I fix this? If I don't need it how would I delete it?

That is the Java Virtual Machine and it is used when a local Java based application is run. It is not intended to be run on its own. Just leave it be.

No, you don't need it, unless you are a developer.

It is a tool to monitor and profile Java processes, and it very useful to developers.

You will notice that this jvisualvm (the executable for this) is missing from here, which is where /usr/bin/jvisualvm re-directs to, through various links.
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin

I actually am a developer. And I noticed that the jvisualvm was in /usr/bin but it wasn't in /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin
