how to get last string ’22’ using java

Answer 1

Depends on your requirement.

If you need the last two chars from a given String, use substring:

String lastToChars = input.substring(input.length()-2);
// if you need that number as integer
int value = Integer.parseInt(lastToChars);

If you need everything after ## (may be a delimiter), do a:

String charsAfterDelimiter = input.split("##")[1];
