java - Main seems to skip over one of my methods -


apologies posting bit of foolish question, cant seem understand why method startendcoords not seem run through main method here:

import java.util.scanner; import java.io.file; import java.io.filenotfoundexception;  public class mazesolver {  // name of file describing maze static string mazefile;  // set global variables static int arrayheight; static int arraywidth; static int startrow; static int startcolumn; static int endrow; static int endcolumn; static int cellsize; static int borderwidth; static int sleeptime; static char [][] maze;  public static void main(string[] args) throws filenotfoundexception {     if (handlearguments(args)) {         maze = readmazefile(args[0]);         startendcoords(maze);           if (solvemaze(startrow, startcolumn))             system.out.println("solved!");         else             system.out.println("maze has no solution.");     } }  // starting & ending points static boolean startendcoords(char[][] mazeasarray){     (int r = 0; r < mazesolver.arrayheight; r++) {         (int c = 0; c < mazesolver.arraywidth; c++) {             if (mazeasarray[r][c] == 's') {                 mazesolver.startrow = r;                 system.out.println(startrow);                 mazesolver.startcolumn = c;                 system.out.println(startcolumn);             }              if (mazeasarray[r][c] == 'e') {                 mazesolver.endrow = r;                 system.out.println(endrow);                 mazesolver.endcolumn = c;                 system.out.println(endcolumn);                 return true;              }          }     } return false; }

the print statements within method not execute, not sure im missing.

thanks help.

full code

it appears readmazefile method intended set of global variables declare, doesn't. instead declares own local variables happen have same names, , sets those. leaves mazesolver.arrayheight @ default value of 0, of course loop instantly bails before running once.

remove int lines in readmazefile set arrayheight , arraywidth. make use , set existing static variables instead of creating new local ones.

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
