How to copy a subset from an array of strings to an array of ints using Groovy?
- by Cuga
I have a String array in a Groovy class (args to a main method):
String[] args
I'd like to convert the 3rd to the last element into a new array of ints. Is there an easier way to do this in Groovy other than:
final int numInts = args.length - 2
final int [] intArray = new int[numInts]
for (int i = 2; i < args.length; i++) {
intArray[i-2]=Integer.parseInt(args[i])
}
I wanted to do:
final int numInts = args.length - 2
final int [] intArray = new int[numInts]
System.arraycopy(args, 2, intArray, 0, numInts)
But it throws a class cast exception.
Thanks!
