What is your implication, that Java is better than Perl because it is newer?
I mean "better" in the sense of which general-purpose development target should you invest your time in as a developer or project manager?
Or if you don't like that: It's a good question. When should you use Perl rather than Java or visa versa? They are clearly competing targets, right? Which one will get your functional and non-functional requirements met with the lowest amount of developer-dollars on setup and maintenance? If it depends on the specifics of the requirements, than how, and in what way does it depend?
It just seems to me, from the comparitively little I know about the subject, that Perl is simply much better for almost all tasks than Java, because it is more popular among developers, you have access to the source and has more technical support in terms of freely available libraries and documentation? It just seems like a more well travelled road. Enlighten me if I'm wrong.
