How can I obtain an interactive shell (like Ruby's irb) for Java?

I spent the last year doing Ruby development, and during that time I discovered irb, which makes running little "code experiments" easy and fun. I've recently switched teams and am now doing Java development, and I've found that I really miss my irb window. I would like to do the same thing for Java, but I don't know how.

I'm using Eclipse (groan), but Eclipse's bells and whistles are not the same thing.

Tried JShell and beanshell. Do suggest JShell over beanshell. Up key will roll back to history lines. Display much user friendly.

Thank you @Anders Sandvig

It can be found in jdk since java 9.

Old question, I know, but jshell: The Java Shell (Read-Eval-Print Loop), is coming in Java 9 (Summer 2017, hopefully).

BeanShell is probably what you're looking for.

Would "Use an Eclipse Java Scrapbook page" be better ;-)

I haven't actually used irb, but if you just want to run code snippets inside of eclipse, then this is a simple way of doing it.

There are a few choices: BeanShell has been around for a long time, and is a great Java REPL.

Another alternative is groovy's groovysh or groovyConsole. While groovy isn't Java in the strict sense, it's great for interactively playing around with Java classes.
