Groovy: How do I sort an ArrayList of String:s in length-of-string order?
Question
How do I sort an ArrayList
of String
's in length-of-string order in Groovy?
Code:
def words = ['groovy', 'is', 'cool']
// your code goes here:
// code that sorts words in ascending length-of-word order
assert words == ['is', 'cool', 'groovy']
There are certainly more than one way to do it - so I'll grant the answer to the person who provides the most elegant solution.
Solution
words = words.sort { it.size() }
To get descending order
words = words.sort { -it.size() }
