Groovy is designed to help you complete things in a fast, more concise and interesting manner on the Java platform, bring Python and Ruby's power to the Java platform.
Groovy can be used as an optional compiler of Java to generate a standard Java bytecode and is used in any Java project. Groovy can be used as a dynamic optional language, such as scriptization Java objects, template, and writing unit test cases.

l Ant scriptization
l Regular expression: Simple script syntax uses regular expressions
l Operators Overload: Simplify the data type of Collection and MAP
