This page was all wrong about final variables.

First, they are not like "const" in C++ since in that language a const field is limited not only to not being reassigned, but there is the additional limitation that only const methods can called on it and it can only be passed as the const argument of other methods.

Second, (non-static) inner classes can freely access any field of the enclosing class, final or not.

Final Local Variables and Arguments

Arguments and local variables can also be declared final. I'm not entirely sure how it works, but I think it should be included in this article.

the same applies to local variables (and function arguments) as to class fields: They must be assigned to at most once (and must be assigned to before being used). Arguments are already assigned when the function body entered. 78.102.120.26 (talk) 06:53, 5 March 2009 (UTC)[reply]
"C++ const is a soft guideline and it can easily be overridden by the programmer" - that's terrible advice, since it implies altering values would be fine like that without mentioning the rapid descent into the realm of undefined behaviour

- I noticed that and removed it immediately. The author definitely did not know what he was talking about. Unsuspected (talk) 15:46, 11 October 2011 (UTC)[reply]
- Please explain. It is well known that code can simply cast away const. Just do an Internet search on "c cast away const". I've heard C/C++ compiler architects say this and that const is just a programmer documentation convenience. This wasn't stated as advice as in what is good style or recommended. It's how the feature works in the C/C++ languages. I will reinstate that sentence. Ramses89 (talk) 18:05, 16 April 2013 (UTC)[reply]

Blank final

Anybody want to add something about blank finals? Otherwise I'll add it at the end of next week when I will have a lot more time.Smallman12q (talk) 02:08, 4 July 2010 (UTC)[reply]
