Why you should care
Unnecessary final modifiers inside final classes should be avoided. Final modifier prevents child classes from overriding a method by prefixing the definition with final. If the class itself is being defined final then it cannot be extended and the modifier is useless.
How we detect
CAST Highlight counts one occurrence each time a “final” artifact is detected within a final class.
