Question

I have the following Groovy code :

def number = "246" as List
def number1= number.subsequences() 
//outputs: [[6], [2, 6], [4, 6], [2], [2, 4, 6], [4], [2, 4]]

Now what i want is, each list in number1 should be returned as int, say for example the second list in number1 should be returned as 26. What i have did was :

number1.each{ it }.collect() as int

Which is not working and throwing an error. Can this be done in any other ways?
Thanks in advance and correct me if am wrong

Answer 1

You need:

number1.collect { it.join() as int }

That will join() each of the numbers in the sub-lists into a String, then convert that String to an int
