Is Android Dalvik Java?

Obviously there are lot of definitions of what Java is or isn't and my opinion on the matter isn't very important to anyone at either Oracle or Google, but I was poking around at some things in an Android application at work looking for something. I ended up getting the system properties from System.getProperties() and present the following comparison:

Hmm. Looks like a lot of the same stuff in properties. This really means nothing other than Google wanted to make the system environment as compatible as possible for prospective developers I guess, but it's just curious to me that while it's not Java, it sure looks like Java does from this one perspective..
