java - Alphabetical value -

The string "code" appears anywhere in the string, return the number of times, for 'D' Any letter will accept, therefore "counting" and "ku" count

Use a regex: 

  string.matches ("Co [az] e")

  int count = 0; Matcher m = Pattern.compile ("with [a-z] e"). Mattress (string); While (m.find ()) {count ++; }

I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request.
