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

Do you need to use regular expressions for this? Would String.lastIndexOf("/") work to find the index, and then use String.substring(int start, int end) with the result? Or is your actual data different and more complicated, requiring regular expressions? With what you provided to split the string on the last /, here's code:

int lastSlash = mystring.lastIndexOf("/");
String start = mystring.substring(0, lastSlash);
String end = mystring.substring(lastSlash + 1, mystring.length);
