This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I recently played around with the Velocity template language available in the Roller Weblogger software powering blogging sites such as JRoller.com and was disappointed to realize that I wasn't able to access the elements of an array in anyway other than using a foreach loop. This is what the documentation suggests:
However, this approach fails because the object returned by the get() method is of type String. So, I needed a way of getting the first element of the array. I couldn't figure out what would do it. I tried square brackets, get(0), and what not. This is what I got working:
I wonder... Is there a better way? There has to be, right?
Thanks Mike. I actually searched the Velocity mailing list (again, this time with more patience) and found this message confirming my fears... I also noticed that RC1 for Velocity 1.4 is out, but decided not to read the change log as the JRoller.com site is not going to upgrade in a while anyway.

Umm. I didn't think of that. I'll go and test it right away.
