const is not used to represent anything. It is reserved, but isn't used.

const is a reserved keyword that is not currently used. Its inclusion as a keyword was to assist compilers in catching out programs where this C++ keyword had been used in error.

final on a reference variable just means that the reference cannot be changed to reference a different object.

As far as I know, const in C++ means that you actually cannot change the object itself (for example by calling mutator methods).
