Method split

Question

String x = "programming_is_fun!_";
String[] array = x.split("_");

Why doesnt the last _ save an empty string in the array?
Thanks for your help

Answer 1

Since last character _ is a separator and there is nothing after it, no element is created in the array. Empty string does not equal to nothingness (null). It is actually a regular string, just without any characters.
