Groovy – a programming language to look into

So what is Groovy? Groovy is like a super version of Java. It can leverage Java’s enterprise capabilities but also has cool productivity features like closures, builders and dynamic typing. If you are a developer, tester or script guru, you have to love Groovy. Below are some of it’s features.

  • 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
