Are you a Java programmer having wrist pain typing a lot (yes, I have!)? Does your mind keep swinging from loving to hating Java? Do you want to become more productive without leaving your world of Java? If so, this presentation is for you. I have been experimenting with Groovy for the last three months and I'm loving it - I am not going back to programming in plan old Java anymore. I'm attaching the full source code (as a .zip file) so that you can try them out on your own. Have fun!
