Java: How to count a character in a String using Loop? -

-

I'm thinking how many times the number of characters written by the user appears in the string that is a user. I have to use loops and if / else statements I think I'm on the right track, but when I'm compiling (using the blues), error message "Icons-variable status can not be found" Any help greatly appreciated Thanks, thanks. 

  string input; String sentence; String letter; Int Time = 0; Int position; Scanner KB = new scanner (System.in); System.out.print ("Please enter a string:"); Input = kb.nextLine (); Sentence = input.toLowerCase (); System.out.print ("Thank you. \ NPlease enter the character you want to count:"); Letter = kb.next (); (Status = 0; condition & lt; = sentence.length (); condition ++) {if (sentence.chartAut (condition) == letter) {times ++; }} System.out.print ("+ + +" + + "sentence + sentence" + + + + letter "has" + bar + "order;)    
 
 
 First of all, your statement contains a typo:  
  sentence. Posotion   
 should be  
  sentence.start (status)   
 Then, you assign to equality test rather than :  
  if (sentence. Chat (status) = letter) should be {  
  
  if (sentence .chart (status) == letter) {  
 After this, you will see a string If there are several ways to resolve this, there is one side (supposedly  letter  is at least one letter):  
  If (sentence. Chat (position) == In the letter and end, you probably can not check the past at the end of the string:  
 for  (position = 0; The status should be   
  
 for  (position = 0; Status & lt; Sentence.length (); Status ++) {

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

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...
