How Android derives from Java

[Andy_Bell]

I'm studing Android language in Android Studio. I know that Anrdoid language is derived by Java, but I desired to review my knowledge on Java programming. So, how is Android libraries similar to Java? Can I find in Java packages and programming-techniques the same components like: Broad Cast Reciver, Intent, Intent Filter and so on?

Classes unique to Android are not necessarily in mainstream Java since they have no relevance outside the Android framework.

Thank you for repaly. So I can't find in Java "component" or resources like Intent, BroadCast Receiver and so on... Isn't it? How can I replace those (i.e. event, event handler, back ground task)?

Not unless they have some context in 'ordinary' Java. If you need specific features then you can check at A-Index (Java Platform SE 7 )[^].
