'?' is a significant character to a regular expression, as is '('.  Escape the
question mark.

(untested)
s = s.replaceAll("\\?", "\"");

Have you considered reading the Javadocs? (JAYF)
<http://java.sun.com/javase/6/docs/api/java/lang/String.html#replaceAl...)>
wherein they link you to an explanation of regular expressions:
<http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.html#sum>

You should always check the Javadocs.  Did you?

hi,
Thanks for the reply

String s = "hello in the (?hell?)";

the output should be of this format

hello in the (“hell”)

its not double quote for hell

i tried this way for replacing the first (? with (“

s = s.replaceAll("\\(?" , "(“");

but i am getting o/p as


(“h(“e(“l(“l(“o(“ (“i(“n(“ (“t(“h(“e(“ (“(“?(“h(“e(“l(“l(“?(“)(“

Those are not regular quotes.

its not double quote for hell

i [sic] tried this way for replacing the first (? with (“

s = s.replaceAll("\\(?" , "(“");

but i [sic] am getting o/p as

(“h(“e(“l(“l(“o(“ (“i(“n(“ (“t(“h(“e(“ (“(“?(“h(“e(“l(“l(“?(“)(“

Read the Javadocs.

You escaped the parenthesis, but not the question mark in the regular
expression.  You didn't even need the parenthesis in the regular expression.

Don't use wacky quote marks.

Read the Javadocs.

i hav gone through the javadocs

and tried this way which worked out for me ,


String s = "hello in the (?hell?) now going to (?heaven?) on the ?
way?)";


s = s.replace("(?" , "(“").replace("?)", "”)").replace("?", "“");


the output is

hello in the (“hell”) now going to (“heaven”) on the “way”)


i have replaced with the wacky quote marks as i need to compare this
string with database string.
