==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:
<syntaxhighlight lang='groovy'>
def x = 10
println "result is $x" // prints: result is 10
</syntaxhighlight>

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

http://groovy-lang.org/closures.html

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".
