Groovy is ...
An agile dynamic language for the Java Platform with many features that are inspired by languages like Python, Ruby and Smalltalk, making them available to Java developers using a Java-like syntax.
Developing web applications , writing shell scripts easily, writing concise, meaningful, test cases using Groovy's JUnit integration, or prototyping and producing real industrial strength applications have never been so concise and groovy.
Groovy works cleanly with all existing Java objects and libraries and compiles straight to Java bytecode in either application development or scripting mode.
Groovy provides powerful additional :
- language conceptual enhancements
- Support for closures - re-usable blocks of code
- Native syntax for lists and maps
- Support the Gof Builder pattern via the notion of builders
- Syntax level regex operators and escape sequences
- Native JavaBean support
- Operator overloading to simplify working with datatypes Collections and Maps
- Polymorphic iteration and autoboxing
- Extension of Java Standard Library through the GDK
- useful standard features to enhance developer productivity such as:
- Groovy Markup for XML, DOM, ...
