java - Scanner delimiter passed with parameter? -

-

I need to parse an input-line character by character, and it will be done in many ways. All around to do this, I'm using the delimiter (""). My question is is do I have to set this delimiter in every way? Or is it enough once in the beginning?

For example 

  zero start () {in the scanner = new scanner (System.in); In.useDelimiter (""); char first = in.next (); (In) readSecond; ...} Zero read second (in the scanner) {//in.useDelimiter (""); & Lt; - Is it necessary? Four seconds = in.next (); ...}   
 Example Input: A5c * vd  
 Thanks!   
 
 
 You do not want to set every time, if you declare and start the scanner object in the class body There are ways that are inside. If you start the scanner in each method, then I think you have to set the delimiter in each method body.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. 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. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
