Why Google Adopted Kotlin for Android?
Google has to get rid of Java, sooner or later. Since the time Oracle took
control of Java and observed Google’s use of JAVA API in Android, it has
been bombarding Google. The last lawsuit was about the commercial use of
Java API: Oracle goes for appeal against Google. and Oracle Won: Happy as
Larry: Why Oracle won the Google Java Android case. Java has become the
Achilles heel for Google.
