Groovy Script
What is a Groovy
Script?
Apache Groovy is an object
oriented and Java syntax compatible programming language built for the Java
platform. This dynamic language has many features which are similar to Python,
Ruby, Smalltalk, and Pero. Groovy source code gets compiled into Java Bytecode
so it can run on any platform that has JRE is installed. Groovy also performs a
lot of tasks behind the scene that makes it more agile and dynamic.
Groovy language can be used as a
scripting language for the Java platform. It is almost like a super version of
Java which offers Java’s enterprise capabilities. It also offers many
productivity features like DSL support, closures, and dynamic typing. Unlike
some other languages, it is designed as a companion, not a replacement for
Java.
