    public static String substring(String str, String startPattern, String endPattern) {
        int begin = str.lastIndexOf(startPattern);
        if (begin == -1) 
            return "";
            
        int end = str.indexOf(endPattern, begin + startPattern.length());
        if (end == -1)
            return "";
        
        return str.substring(begin + startPattern.length(), end);
