How to check if element in groovy array/hash/collection/list?

How do I figure out if an array contains an element? I thought there might be something like [1, 2, 3].includes(1) which would evaluate as true.

Solution

  • .contains() is the best method for lists, but for maps you will need to use .containsKey() or .containsValue()

    [a:1,b:2,c:3].containsValue(3)
[a:1,b:2,c:3].containsKey('a')
