Map with Key as String and Value as List in Groovy

Question

Can anyone point me to an example of how to use a Map in Groovy which has a String as its key and a List as value?

Answer 1

def map = [:]
map["stringKey"] = [1, 2, 3, 4]
map["anotherKey"] = [55, 66, 77]

assert map["anotherKey"] == [55, 66, 77]
