Groovy Closure Example

A closure is an anonymous code block that can take arguments, return value, and also can be assigned to a variable. When it comes to Groovy, a closure can contain a variable scope defined outside of the closure expression. Groovy offers extended features to formal closure definition. By using this features, we can write our code more dynamically by applying closures to functions as parameter, caling anonymous code blocks inside functions, etc…. Let’s see closure in action with supporting examples.
