Question

Probably not the best title, but I’ll explain:
I have an array of objects – lets call them Person.
Each Person has a Name. I want to create an array of Name respectively.

Currently I have:

def peopleNames = new ArrayList<String>()

for (person in people)
{
    peopleNames.add(person.name)
}

Does groovy provide a better means of doing so?

Answer 1

Groovy provides a collect method on Groovy collections that makes it possible to do this in one line:

def peopleNames = people.collect { it.name }
