Groovy: Print elements of list without using a counter and list size

In Groovy, non-empty list is evaluated to true, whereas empty list is evaluated to false. We can use the same to traverse the list.

HelloWorld.groovy

primes = [2, 3, 5, 7, 11]

while(primes){
 number = primes.remove(0)
 println "$number "
}

Output

2

3

5

7

11
