Question

Lets say I have a array defined in Groovy like this

def int[] a = [1,9]

Now I want to convert this array into a int variable say a1 such that a1 has the value as 19(which are the array values in the a) any way to do this?

Answer 1

1) you don’t need the def:

int[] a = [0,9]

2) What do you mean by 09? Isn’t that 9? How are you seeing this encoding working?

If you mean you just want to concatenate the numbers together, so;

[ 1, 2, 3, 4 ] == 1234

Then you could do something like:

int b = a.collect { "$it" }.join( '' ) as int

which converts each element into a string, joins them all together, and then parses the resultant String into an int
