java - Cannot find string -


i'm messing around code see can , can't , i'm creating simple log in program , reason can't seem find 1 of strings. here's code:

import java.util.scanner;  public class login {     public static void main(string[] args) {         scanner input = new scanner(system.in);          system.out.print("username: ");         string user = input.next();         system.out.print('\f');          while (true) {             system.out.print("pass: ");             string pass = input.next();             system.out.print('\f');              system.out.print("password again: ");             string pass2 = input.next();             system.out.print('\f');              if (pass.equals(pass2)) {                 system.out.println("*passwords match*");                 system.out.println("");                 break;             } else if (!pass.equals(pass2)) {                  system.out.println("*passwords don't match, please try again*");                  system.out.println("");             }          }         system.out.println("user: " + user);         system.out.println("pass: " + pass);     } }

it can't find string pass. don't know if it's reserved word or not when tried changing string password instead of pass still couldn't find it. nice

you using pass outside of can used. if declare within main method, code work. basically, being used outside of scope of while loop must initialized somewhere. stated, don't have worry pass2 being declared elsewhere since main functionality resides purely within scope of loop

import java.util.scanner;  public class login {     public static void main(string[] args) {         scanner input = new scanner(system.in);         string pass,user;         system.out.print("username: ");         user = input.next();         system.out.print('\f');          while (true) {             system.out.print("pass: ");             pass = input.next();             system.out.print('\f');              system.out.print("password again: ");             string pass2 = input.next();             system.out.print('\f');              if (pass.equals(pass2)) {                 system.out.println("*passwords match*");                 system.out.println("");                 break;             } else if (!pass.equals(pass2)) {                  system.out.println("*passwords don't match, please try again*");                  system.out.println("");             }          }         system.out.println("user: " + user);         system.out.println("pass: " + pass);     } }

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
