String Programming
TODO next time I need it.
Single-Quoted vs. Double-Quoted Strings
Groovy has both double-quoted and single-quoted String literals. The main difference is that double-quoted String literals support String interpolation:
def x = 10
println "result is $x" // prints: result is 10
Working with Closures
Defining a Closure
def myClosure = { e -> println "Clicked on $e.source" }
Implicit Paramenter
When a closure does not explicitly define a parameter using the '->' syntax, the closure 'always defines an implicit parameter named "it".
