If I am given an string which is the repsentation of an array of int like below
String d = "[2,3,4,5]"
How I convert to an array of string?
String[] f = convert d to array of String
Also how I convert to an array of int?
int[] f = convert d to array of int
I was looking for other solutions, since my values contained strings including dots in them and found this.
This code should work for you:
"[1,2,3]".tokenize(',[]')*.toInteger()
You can use Eval.me like so:
String[] f = Eval.me( d )*.toString()
Or
int[] i = Eval.me( d )
Be careful though, as if this String is entered by a third party, it could do nasty things and is a huge security risk... To get round that, you'd need to parse it yourself with something like:
def simplisticParse( String input, Class requiredType ) {
input.dropWhile { it != '[' }
.drop( 1 )
.takeWhile { it != ']' }
.split( ',' )*.asType( requiredType )
}
String[] s = simplisticParse( d, String )
int[] i = simplisticParse( d, Integer )
String[] or int[] to List and you'll have a List of objects instead :-)
