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.

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

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
