>From java doc for String.split (asterisks/bold added for emphasis):

The array returned by this method contains each substring of this string
that is terminated by another substring that matches the given expression or
is terminated by the end of the string. The substrings in the array are in
the order in which they occur in this string. *If the expression does not
match any part of the input then the resulting array has just one element,
namely this string.*
