Then I’ll cover the Basics, Math, Strings, Output, Input, Lists, Maps, Range, Conditonals, Looping, Methods, Closures, File IO, OOP and a ton of other topics in between. By the end you’ll learn as much as you’d learn in a standard 250 page book on Groovy.

May 03, 2022 15:10 pmGreetings, Derek!
I needed to get the basics behind Groovy so that I can do a task of mine and your video was excellent for me personally.
I've background in other languages, so this video was easy for me to follow and I was fascinated by the ability to use range in side of Switch statement – just wow 馃榾
Happy New Year by the way!

May 03, 2022 15:10 pmIt's a good one. I didn't expect to encounter closures and pre-existing set methods in classes.

May 03, 2022 15:10 pmAt 54:45, is it possible to return the index of the array item that matches "Sue"?
VideoNOLA
May 03, 2022 15:10 pm33:30 Would the range 'r'..'r' produce (a) 'r, r', (b) 'r' or (c) null?
VideoNOLA
May 03, 2022 15:10 pm26:30 I honestly had not expected array indexing to be 1-based in Groovy, but if so, that's brave and probably a boon for n00bs. <20 seconds lay-terrr> "Oops, the arrays are zero-based, psych!"

May 03, 2022 15:10 pmThanks for this primer. I have a new tool that uses this language for automations.
SweetGazelle
May 03, 2022 15:10 pmAlmost 6 years later, this comes as a lifesaver. You are simply AMAZING. Your way of constructing a video is TOO good, I have been looking far and wide for this kind of format, where the information is simply given in a concise manner, and you delivered even more! It's a struggle to watch a 2 minute video for me, but I sat through the whole hour and didn't feel the time passing. Every single information is vital, and this answered every single question I had in the most pleasant manner. I CANNOT thank you enough for your tremendous effort and your lovely soul, THANK YOU!!

May 03, 2022 15:10 pmIf you got an error like this "groovy: JAVA_HOME is not defined correctly, can not execute: /usr/libexec/java_home -v 1.8.301.09 (x86_64)/bin/java" while trying to execute the groovy interpreter/compiler
It is because java now gives the output version parsed different (before=version, architecture now=version (architecture)", so instead of typing export JAVA_HOME=`/usr/libexec/java_home -v 1.8.301.09 (x86_64)` delete both parenthesis and put a coma to separate the version from the processor architecture and type something like this:
export JAVA_HOME=`/usr/libexec/java_home -v 1.8.301.09, x86_64`
