I just ran into one thing I wish I had included in the Scala Cookbook that I didn’t include: How to access a
var field in a Scala object from your Java code.
In short, if you have a field named
appName defined in a Scala object, like this:
val appName = "Little Logger"
and you want to access it from your Java code, you’ll write your Java code like this:
As you can see, you need to access the field as a “getter” method. That’s because Scala generates getter methods for public
val fields, and getter and setter methods for public
var fields, and you need to access the Scala fields using these generated methods.
