Groovy是一種基于JVM的敏捷開發語言，它結合了Python、Ruby和Smalltalk的許多強大的特性。

Groovy 主要的特點包括：

• 是一個基于Java虛擬機的敏捷動態語言。

• 構建在強大的Java語言之上 并添加了從Python，Ruby和Smalltalk等語言中學到的諸多特征。

• 為Java開發者提供了現代最流行的編程語言特性，而且學習成本很低（幾乎為零）。

• 支持DSL（Domain Specific Languages領域定義語言）和其它簡潔的語法，讓你的代碼變得易于閱讀和維護。

• Goovy擁有處理原生類型，面向對象以及一個Ant DSL，使得創建Shell Scripts變的非常簡單。

• 在開發Web，GUI，數據庫或控制臺程序時 通過減少框架性代碼 大大提高了開發者的效率。

• 支持單元測試和模擬（對象），可以簡化測試。

• 無縫集成 所有已經存在的 Java對象和類庫。

• 直接編譯成Java字節碼，這樣可以在任何使用Java的地方 使用Groovy。
