Is there something like python's interactive REPL mode, but for Java?
I'm looking for a REPL shell that I can use to test out snippets of Java code. Either a desktop app, or a web app (like the Groovy web console). Ideally, commonly used Java packages like:
java.io.*
java.util.*
should be automatically imported, so that I can copy and paste code from a class without having to add a bunch of imports. Does such a thing exist?
