I would like a regular expression or otherwise some method to remove the last character in a string if and only if that character is '/'. How can I do it?

If you are having a string with special characters and want's to remove/replace them then you can use regex for that. Use this code: Regex. Replace(your String, @"[^0-9a-zA-Z]+", "")
The idea is to use the deleteCharAt() method of StringBuilder class to remove first and the last character of a string. The deleteCharAt() method accepts a parameter as an index of the character you want to remove. Remove last character of a string using sb. deleteCharAt(str.
Use the . rstrip() method to remove whitespace and characters only from the end of a string.
string = string.replace(/\/$/, ""); $ marks the end of a string. \/ is a RegExp-escaped /. Combining both = Replace the / at the end of a line.
