Question

A basic String handling question..I have a tokenized String like val1.val2.val3…..valN
How do I get the last word valN from the string above.

Answer 1

If you pass a negative index n to the subscript operator in a List, you get n-th last element. Therefore, the -1 element is the last one:

def words = 'val1.val2.val3'
def last = words.tokenize('.')[-1]
assert last == 'val3'

Update: You also have the, arguably more readable, last method:

def last = words.tokenize('.').last()
