Java, the Language Needs a Runtime

The Android SDK was launched in late 2007 and they said, hey programmers, try out our new platform. And then word came down from on high somewhere that that single language was going to be Java. So if you give them a language that they already know because they probably used it A in school and B in their enterprise jobs elsewhere, then you've made it easy for them to understand the language of writing Android apps as well. It's something like the original slogan coming out of Sun was write once run everywhere.
