Is there any program like LINQPad for Java?

JPad - A java scratchpad for running snippets

Since I also couldn't find one I've decided to write one. Currently it can:

1. Run java snippets (no class / imports / public blah... needed).
2. Contains drivers for MS/MySQL/Postgres.
3. Output results as HTML tables

It's very rough but I will add to it over time. Feedback is definitely welcome.

You can use the Groovy web console ; it's possible to speak java in groovy land.

Java Snippet Runner: Does something similar to Linqpad (jar file, not just for macs)

Code Runner (Commercial): for Mac's only, it'll run code snippets in Java, and lots of other languages too (e.g. Objective C)
