java - Why my variables cannot receive a value (interface) -

-

I have a problem sending values ​​to variables. Why when my input is in value, why can not my variable get the value? I have no idea of ​​doing this ... import java.io. *; Public class student app {public static zero main (string [] args throws IOException {student student object = new grade result}; studentObject.getName (); Student StudentObject 2 = New grade Resolve (); StudentObject2.getIdNum (); Student student object 3 = new grade resal (); studentObject3.getMark (); Student student object 4 = new grade resal (); studentObject4.setName (); Student studentObanks 5 = new grade Ristil (); StudentObject5.setIdNum (); Student student object 6 = new grade resal (); studentObject6.setMark (); Student StudentObject 7 = New grade Result (); StudentObject7.showGrade (); Student Student Object 8 = New grade Resolve (); StudentObject8.showResult (); } Interface student interface {zero getName () throws IOException; Zero getIdNum () throws IOException; Zero setname (); Zero set idnam (); Zero getMark () throws IOException; Zero setmark (); } Interface Student Student Interface (Results of zero showing); Zero show grade (); } Class Grade Result Student {String Name, Name 2, Name 3; Applies; int a, sign; Public zero getName () throws IOException {InputStreamReader inStream = new InputStreamReader (System.in); Buffettder stdin = new buffertder (instream); System.out.print ("Please input your name:"); Name = stdin.readLine (); } Public Zero getIdNum () throws IOException {BufferedReader stdin = new BufferedReader (New InputStreamReader (System.in)); System.out.print ("Please input your ID number:"); Name2 = stdin.readLine (); A = integer Parasent (name 2); } Public Zero Setnam () {System.out.print ("Your Name:" + Name); } Public Zero SetIDNUm () {System.out.print ("\ nYour ID number:" + name2); } Public zero getmark () throws IOException {BufferedReader stdin = new BufferedReader (New InputStreamReader (System.in)); System.out.print ("Please input your mark:"); Name3 = stdin.readLine (); Mark = integer Parasent (name 3); } Public Zero Setmark () {System.out.print ("\ nYour Mark:" + Icon); } Results of public zeros () {if ((Mark> = 40) & amp; amp; (Mark & ​​lt; = 100)) {System.out.print ("\ nYou are near"); } And {System.out.print ("\ nYou have failed"); }} Public Zero Show Grade () (if ((Mark> = 80) & amp; amp; (Mark & ​​lt; = 100)) {System.out.print ("\ n Your grade is one"); } And if ((Mark> = 65) & amp; amp; (Mark & ​​lt; = 80)) {System.out.print ("\ nYour grade is B");} And if ((Symbols & Gt; = 50) & amp; amp; amp; (Symbols & lt; = 65)) {System.out.print ("\ nYour grade is C");} And if ((Mark> = 40) & amp; amp; amp; (Mark & ​​lt; = 50)) {System.out.print ("\ nYour grade is D");} Else {System.out.print ("\ nYour grade is E." );}}}

I'm not sure who is my fault Should use the context reference or just call the main method.

The best solution is to work with your Grade Result class 

  Private static string name, name 2, name 3 has to do the following: Private Static Int a, Symbol;   
 This will work ..!  
 Output:  
  Please input your name: Mohammed Please enter your ID number: 10001 Please enter your mark input T: 85 Your name: Mohammad your ID number: 10001 Your Mark: 85 your grades you have PASS

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...
