Join a string array to a string in Java - like join() in Perl

 An implementation of Perl like join() function in Java:

        public static String join(String[] strings, String separator) {

            StringBuffer sb = new StringBuffer();

            for (int i=0; i < strings.length; i++) {

                if (i != 0) sb.append(separator);

                     sb.append(strings[i]);

                 }

                 return sb.toString();

        }

Enjoy!
