Array of strings in groovy

Question

In ruby, there is a indiom to create a array of strings like this:

names = %w( lucas Fred Mary )

Is there something like that in groovy?

Solution 1

Most of the time you would create a list in groovy rather than an array. You could do it like this:

names = ["lucas", "Fred", "Mary"]

Alternately, if you did not want to quote everything like you did in the ruby example, you could do this:

names = "lucas Fred Mary".split()

Solution 2

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

[tim_yates]

or indeed ["lucas", "Fred", "Mary"] as String[]

[Dónal]

or (String[])['Lucas', 'Fred', 'Mary']

But sometimes APIs require a String[], so providing both options in the answer would be nice.

I think toArray() returns an Object[], not a String[].

Nice. I was actually looking to make an array, convert to list and then check if it contains a string, but I can skip the middle part by just creating the list directly and calling contains(). That's Groovy!
