         while (i < length) {
           iter.next();
           iter.set(a[offset + i++]);
         }
         
        However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.

      • replaceAll

        public final void replaceAll​(DoubleUnaryOperator operator)
        Replaces each element of this list with the result of applying the operator to that element.

        WARNING: Overriding this method is almost always a mistake, as this overload only exists to disambiguate. Instead, override the replaceAll() overload that uses the JDK's primitive unary operator type (e.g. IntUnaryOperator).

        If Java supported final default methods, this would be one, but sadly it does not.

        If you checked and are overriding the version with java.util.function.XUnaryOperator, and still see this warning, then your IDE is incorrectly conflating this method with the proper method to override, and you can safely ignore this message.

        Specified by:
        replaceAll in interface DoubleList
        Parameters:
        operator - the operator to apply to each element
        See Also:
        List.replaceAll(java.util.function.UnaryOperator<E>)
        Implementation Specification:
        This method just delegates to the interface default method, as the default method, but it is final, so it cannot be overridden.
