Groovy Learning Curve

Hi!

How much time a person that has experience with Java usually takes to learn Groovy?

There's no good way to answer that. No one knows how well you know java and how quickly you pick up new things. That said, groovy is as close to Java as any other JVM based scripting language. It shouldn't take anyone with a good understanding of java and some smarts to pick up Groovy, as a language, anywhere from a few hours to a few days, depending on which bits you need when.

Found the following in Groovy site....

Groovy...

* is an agile and dynamic language for the Java Virtual Machine
* builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk
* makes modern programming features available to Java developers with almost-zero learning curve
* supports Domain-Specific Languages and other compact syntax so your code becomes easy to read and maintain
* makes writing shell and build scripts easy with its powerful processing primitives, OO abilities and an Ant DSL
* increases developer productivity by reducing scaffolding code when developing web, GUI, database or console applications
* simplifies testing by supporting unit testing and mocking out-of-the-box
* seamlessly integrates with all existing Java objects and libraries
* compiles straight to Java bytecode so you can use it anywhere you can use Java

So, if you are good in Java.... I think you need not to think twice to learn a similar language. If you understand well, you get one more new language added in your CV. Otherwise you won't loose anything other than spending some time in doing R&D for your own learning after all....

Hi all,

I am new to Groovy. I want to integrate Groovy Rule Engine in my application. But before that want to try a simple HelloWorld rule. I tried searching web for examples for it, but could not find a good one.

Can someone please give me some example link URLs.

Thanks,
Vir
