Answer 1

Adapted from Matcher.replaceAll

boolean result = matcher.find();
if (result) {
    StringBuffer sb = new StringBuffer();
    do {
        String tokenKey = matcher.group(1); // Ex: fizz
        String replacement = Matcher.quoteReplacement(tokensMap.get(tokenKey));
        matcher.appendReplacement(sb, replacement);
        result = matcher.find();
    } while (result);
    matcher.appendTail(sb);
    return sb.toString();
}
