Question

I want to remove ) character from the end of a string through a regex.

E.g If a string is UK(Great Britain) then I want to replace the last ) symbol.

Note:

1). The regex should remove only the last ) symbol, doesn’t matter how many ) symbols are present in the string.

Answer 1

Please don’t use a regex for this simple task.

// If the last ) might not be the last character of the String
String s = "Your String with) multiple).";
StringBuilder sb = new StringBuilder(s);
sb.deleteCharAt(s.lastIndexOf(')'));
s = sb.toString(); // s = "Your String with) multiple."

// If the last ) will always be the last character of the String
s = "Your String with))";
if (s.endsWith(")")) 
    s = s.substring(0, s.length() - 1);
// s = "Your String with)"
