Why doesn't Java have optimization for tail-recursion at all?

    https://softwareengineering.stackexchange.com/questions/272061/why-doesnt-java-have-optimization-for-tail-recursion-at-all
    However, why doesn't Java at least have tail-recursion optimization for static methods and enforce proper way to call static methods with the compiler? Why doesn't Java have any support at all for tail-recursion? I am not sure if there is any difficulty here at all.

    I'm not sure COBOL does (it certainly didn't at one time), but I can't quite imagine anybody caring much either. Fortran has since Fortran 90, but requires that you use the recursive keyword to tell it that a subroutine is recursive.. PL/I was pretty much the same -- recursion was supported, but you had to explicitly tell it what procedures were recursive.

    Recursion. Fortran 77 did not explicitly allow recursive functions and subroutines, although there were several ways around this eg Fortran Examples.From Fortran 90 onwards, recursive functions and subroutines could be declared and used freely.

    Recursion in the abstract is a useful approach to solving problems, which is why you should learn about it even if you don’t write recursive code. There are three basic problems with recursion: * If your recursive function doesn’t terminate or tak...

    I'm not sure what you mean by "it." Just because some compiler vendors may have supported non-standard extensions that allowed recursion does not mean you can claim the language supported it in general. GP is right: Fortran, as a standard, did not support recursion until 1990.2/5(86)

Fortran 77 does not support recusive functions (Because in Fortran 77, local (and parameter) variables are NOT created when execution enters the recusive function ) However, Fortran 90 does.
