regex - Java scoping issue -

-

Can anyone see my code and try to help me figure it out? This is a regex app that parses user commandline questions. 

  Public class interrupt commmissions {public static zero major (string [] args) {string A; Command c = new command (); Java.util.Scanner Reader = New Scanner (System.in); System.out.println ("Enter command:"); A = Reader NXtine (); // Scanning string user input string line = a; // command command string pattern 1 = "(? Lt; =) - ([o] \\ s). Filter order string pattern 2 =" (? & Lt; = (-) ([ F] \\ s). // Create Pattern Object Patterns r1 = Pattern.compile (pattern1); Pattern r2 = Pattern.compile (pattern2); // Creating Matter Objects Mater M1 = R 1. Matter (A) ; Matcher M2 = R 2. Mattere (A); // If order match (m1.find ()) {string s1 = m1.group (0); println (s1); ** it works ** System.out.println (c.returnActions1 (s1)); ** says that the print is not applicable for debate **} and if (m2.find ()) Writing s2 = m2.group (0); println (s2); ** This works ** System.out.println (c.returnActions2 (s2)); ** says that print is not applicable for arguments * *} And {System.out.println ("no matching for given input");}} public class command {string A; public zero return verb 1 (string s1) {string [] command = s1.split ( ","); (Int i = 0; i & lt; commands.length; i ++) {if (commands [i] .equals ("TITLE")) {// select "TITLE" & lt ; Dataframe & gt; } And if (commands [i] .equals ("DATE")) {// Select "DATE" from & lt; Dataframe & gt; }}} Public zero return action 2 (string s2) {string [] command = s2.split (","); For (int i = 0; i & lt; commands.lampper; i ++) {if (commands [i] amends ("TITLE")) {// ORDER & lt; Dataframe & gt; "TITLE") and if (commands [i] .equals ("DATE")) {// ORDER & lt; Dataframe & gt; "DATE" by}}}}}   
 Any thoughts on what's wrong? I'm sure Im has failed to accurately scope my variables, or maybe they should normally get instant. The problem arises when I pass my main variables to other class methods in the main.   
 
 
 assuming that you really want the command to be an internal class:  
  command c = new command ();   
 Fails to compile with an error  
  Error: non-static variable can not be referenced from a static reference   
 command  static  will have to take care of this problem.  
 Then,  
  System.out.println (c.returnActions1 (s1));   
 fails to compile with error  
  Error: 'zero' type is not allowed here   
 Which is a logical  
  the result of definition of return as a public zero return action 1 (string s1) {/ code>  
 As I do not know In fact, what you want to do in that method, I can only suggest changing its return type  
  public string return No Action 1 (string S1) {  
 and to return the return return statement to that method.

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...
