Indeed, right pain in the @@@@.

Primitive types are scheduled for removal, leaving only reference
types.

Biggest mistake The Green Team made. Fixed by Groovy. Oh and Scala,
Ceylon, Kotlin.

Why would you want them for a JVM-based machine, there is no
possibility of reification of type parameters, type erasure and all
that mess. Scala, Kotlin, etc. have to create a vast infrastructure to
deal with this.

Setters, getters and mutable properties are, or should be, anathema.
They turn an object oriented programming language into an imperative
procedural one without encapsulation.

You can have as many classes as you want per file, but only one of
them can be public.

In Java. And Scala. Groovy, Kotlin, and Ceylon do things differently,
the programmer can treat the JVM as having top-level functions.
