You do have a Void type in Java if you really must specify a return type and don’t want to return anything e.g. services and their tasks in JavaFx. The Task must have a return type thus you can use Void if the task doesn’t actually return anything.
Well, yeah, but that Void type is different than the Void type in Haskell.
The Haskell-Void says that the function never returns. So, for example, if the function always goes into an infinite loop. Or only ever throws an exception or does a System.exit(0). You cannot portray that in Java, to my knowledge.
