It integrates smoothly with any Java program, and immediately delivers to your application powerful features, including scripting capabilities, Domain-Specific Language authoring, runtime and compile-time meta-programming and functional programming.

Apache Groovy

Feature

  • Is an agile dynamic language based on Java virtual machine.
  • Built on the powerful Java language and added many features learned in languages ​​like Python, Ruby and Smalltalk.
  • Offers Java developers the most modern programming language features in the world, and low learning costs (almost zero).
  • Support DSL (Domain Specific Languages ​​Domain Definition Language) and other concise syntax, make your code easier to read and maintain.
  • Goovy has native type handling, object orientation, and an Ant DSL that make it easy to create shell scripts.
  • Developers efficiency is greatly improved by reducing framework code when developing Web, GUI, database or console applications.
  • Support unit testing and simulation (object), can simplify the test.
  • Seamless integration of all existing Java objects and libraries.
  • Compile directly into Java bytecode so Groovy can be used anywhere Java is used.
