Come now, we have IDEs for that. But seriously, Java users are not stuck in the 1990s, even if your gibes at its expense are, so perhaps you should revisit it. :)

Not just IDE's but also scripting languages like Groovy (the scripting version), its predecessor Beanshell, other less often used ones like Nashorn and Xtend, and even Clojure which doubles as a systems language.

NB: By "Groovy (the scripting version)" I mean the component of Groovy which was Beanshell with closures and collections syntax added, but before the meta-object protocol was. So Groovy as used by Gradle rather than Groovy as used by Grails.
