Java: Getting a substring from a string starting after a particular character

A very simple implementation with String.split():

String path = "/abc/def/ghfj.doc";
// Split path into segments
String segments[] = path.split("/");
// Grab the last segment
String document = segments[segments.length - 1];

String example = "/abc/def/ghfj.doc";
System.out.println(example.substring(example.lastIndexOf("/") + 1));

what have you tried? it's very simple:

String s = "/abc/def/ghfj.doc";
s.substring(s.lastIndexOf("/") + 1)
