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.

Answer 1

words = words.sort { it.size() } 

To get descending order

words = words.sort { -it.size() }
