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?

Groovy reuses the list notation for arrays, but to make such literals arrays, you need to explicitly define the type of the array through coercion or type declaration. You can also create multi-dimensional arrays.
In Groovy, you can access array item by using square bracket with an index ( [index] ) or using getAt(index) function.
[:] creates an empty Map. The colon is there to distinguish it from [] , which creates an empty List. This groovy code: def foo = [:] is roughly equivalent to this java code: Object foo = new java.util.LinkedHashMap();
A String literal is constructed in Groovy by enclosing the string text in quotations. Groovy offers a variety of ways to denote a String literal. Strings in Groovy can be enclosed in single quotes ('), double quotes (“), or triple quotes (“””). Further, a Groovy String enclosed by triple quotes may span multiple lines.
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() If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
