除了动态类型，是什么让Ruby“比Java更灵活”？

I've been using Java almost since it first came out but have over the last five years gotten burnt out with how complex it's become to get even the simplest things done. I'm starting to learn Ruby at the recommendation of my psychiatrist, uh, I mean my coworkers (younger, cooler coworkers - they use Macs!). Anyway, one of the things they keep repeating is that Ruby is a "flexible" language compared to older, more beaten-up languages like Java but I really have no idea what that means. Could someone explain what makes one language "more flexible" than another? Please. I kind of get the point about dynamic typing and can see how that could be of benefit for conciseness. And the Ruby syntax is, well, beautiful. What else? Is dynamic typing the main reason?I've been using Java almost since it first came
