Question

Java

What is the difference between android and java?
Of course, I understand that java is yap, android is os. But they write textbooks on android, android courses, android training, is that a framework? And what do they write on in 'anroyd'?

Answer 1

You are correct in saying
java is the programming language
android is the operating system.
applications are written in java using the android framework
, there are books purely on java, and there are books on the android framework, for those who know java
