If your user defined types implement equals as you need, then you can just do
list1 == list2. Owen’s solution allows equality when order is different or
there are duplicates.
This also sounds like a zip operation, which took me a really long time to find
in Groovy but I recently found it:
def letters = ['a', 'b']
def numbers = [1, 2]
assert ['a1', 'b2'] ==
GroovyCollections.transpose(letters, numbers).collect { it[0] + it[1] }
In your case of testing a condition (equality) you can use
any<http://docs.groovy-lang.org/latest/html/groovy-jdk/java/lang/Iterable.html#any(groovy.lang.Closure)>
method instead of collect.

Hi,
I want to know if it's possible to have a closure that can iterate over 2 equal
length lists? The equivalent of doing list1.each, list2.each { ... }, where
each list is a list of an user-defined type.
Basically I want to compare elements in the lists to see if they are equal.
Thanks.
Les
