I'm surprised nobody mentioned Kotlin. It's similar but better, simple enough that reading/writing code is close to pseudocode. Google has moved towards officially supporting Kotlin instead of Java for Android development.
”Today we’re announcing another big step: Android development will become increasingly Kotlin-first. Many new Jetpack APIs and features will be offered first in Kotlin. If you’re starting a new project, you should write it in Kotlin”
“Just use Kotlin” doesn’t help for the licensing issue, though, if you keep using Oracle’s JVM.
