Replace characters in a String, in a specific location

I have the following string;

String s = "Hellow world,how are you?\"The other day, where where you?\"";

And I want to replace the , but only the one that is inside the quotation mark \"The other day, where where you?\".

Is it possible with regex?

String s = "Hellow world,how are you?\"The other day, where where you?\"";
Pattern pattern = Pattern.compile("\"(.*?)\"");
Matcher matcher = pattern.matcher(s);
while (matcher.find()) {
    s = s.substring(0, matcher.start()) + matcher.group().replace(',','X') + 
            s.substring(matcher.end(), s.length());                                  
}

If there are more then two quotes this splits the text into in quote/out of quote and only processes inside quotes. However if there are odd number of quotes (unmatched quotes), the last quote is ignored.

If you are sure this is always the last "," you can do that

String s = "Hellow world,how are you?\"The other day, where where you?\"";
int index = s.lastIndexOf(",");
if( index >= 0 )
    s = new StringBuilder(s).replace(index , index + 1,"X").toString();
System.out.println(s);

Hope it helps.
