Find Last Index Of by Regex in Java

Question

i have a string %/O^/O%/O. I want to find the last / to split the string. First attemp was: \\/[POL]$ but that gets it inclusive the \"O\"

Answer 1

/(?=[^/]*$)

will match a / that isn't followed by any more /s. To split on it, use

String[] splitArray = subjectString.split("/(?=[^/]*$)");
