java - How do I get this try catch to loop until it no longer gets an error? -

-

I have a try block that is checking whether the input is from the scanner or not. But instead of loop it twice and asks how many people have to send .. Then say error: no number. Actually without prompting the user to enter a different number 

  int peopleToSend = 0; // I tried to catch one ... but it is not working for whom I was planning for ... while (locosed & lt; 1 || people suspect & gt; people olive ()) {try { system.out.print ("\" How many people do you want to send out? 1 - "+ PeopleAlive () +": "); PeopleToSend = scan.nextInt (); } Hold (exception e) {System.out.println ("Error: no number."); }}   
 An example of output when entering someone other than an int.  
  How many people do you want to send? 1 - 22: Error: No number How many people do you want to send out? 1 - 22: Error: No number How many people do you want to send out? 1 - 22: Error: No number How many people do you want to send out? 1 - 22: Error: No number * Loops forever *    
 
 
 One  Add a scan. Nxt (); After the statement error:  
  hold (exception e) {System.out.println ("Error: no number."); Scan.next (); }

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
