Another shortcut in Groovy isOperator Overloading.
You can type something like this:
def d = new Date()
println d.next()
(1..3).each{println d++}

This code will print:
Mon Jan 11 12:06:11 PST 2010
Sun Jan 10 12:06:11 PST 2010
Mon Jan 11 12:06:11 PST 2010
Tue Jan 12 12:06:11 PST 2010

assuming that today’s date is January 10th at 12:06 PST in 2010.

This code will instatiate a new date and print the next date.
Then it will print three more dates starting from today’s date.

The d++ will call the next method.

Here are other operator overloading:

For example:

def b=new Date()
def v = new Date()
println “b”+b
println “v”+d
if(b.equals(v))
println “true”
else
println “false”
