I'm not sure whether I'm answering your question or not ...

The String class has a replace method that will replace all occurrences of a single character with another character and return the resulting String object. But neither String nor StringBuffer have methods that allow all occurrences of a substring to be replaced with another substring. Here is a fairly efficient implementation that you might try. First argument is source string, second is the search substring, third is the replacement substring.

   public static String replaceSubstring(String str, String pattern, String replace) {
       int slen = str.length();
       int plen = pattern.length();
       int s = 0, e = 0;
       StringBuffer result = new StringBuffer(slen);
       char[] chars = new char[slen];

       while ((e = str.indexOf(pattern, s)) >= 0) {
           str.getChars(s, e, chars, 0);
           result.append(chars, 0, e - s).append(replace);
           s = e + plen;
       }
       str.getChars(s, slen, chars, 0);
       result.append(chars, 0, slen - s);
       return result.toString();
   }

Or if you are familiar with Perl, and are able to include the PerlTools.jar on your classpath this an be executed much faster and with less code using regular expression.

> and with less code ...

Depends if you count the additional code downloaded in PerlTools.jar.
