UnnecessaryFinalModifier

When a class has the final modifier, all the methods are automatically final and do not need to be tagged as such.


    
//ClassOrInterfaceDeclaration[@Final='true' and @Interface='false']
    /ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration
        [count(./Annotation/MarkerAnnotation/Name[@Image='SafeVarargs' or @Image='java.lang.SafeVarargs']) = 0]
    /MethodDeclaration[@Final='true']
    

Example(s):



public final class Foo {
    // This final modifier is not necessary, since the class is final
    // and thus, all methods are final
    private final void foo() {
    }
}
