On the "Naming Conventions" doc page, it says in the [Constants, Values, Variable and Methods](http://docs.scala-lang.org/style/naming-conventions.html#constants-values-variable-and-methods) that: > Constant names should be in upper camel case... (similar to Java’s static final members) Java does not follow upper camel case for constants naming convention, according to the [Code Conventions for the Java TM Programming Language](http://www.oracle.com/technetwork/java/codeconventions-135099.html): > The names of variables declared class constants and of ANSI constants should be all uppercase with words separated by underscores ("_").
