java - Having trouble with writing a .txt flie -


so having trouble getting program not throw nosuchelement exceptions @ me. when input owner info, throws exception after second owner no matter owner input:

jones; 221 smith st; arlington; texas; 76019  smith; 7345 lane rd; dallas; texas; 75000  willis; 596 dale lane; fort worth; texas; 76123

here's code:

import java.util.formatter; import java.util.scanner; import java.util.nosuchelementexception; import java.util.stringtokenizer;  public class writefile {  public static void main(string[] args) {      formatter output;     try     {         output = new formatter("owners.txt");         system.out.println("file accessed");          system.out.println("please enter owner information. separate     information semicolons please:");         scanner input = new scanner(system.in);          while(input.hasnext())         {             try             {                  string owner = input.nextline();                 string[] tokens = owner.split(";");                  output.format("%s %s %s %s %d%n",input.next(), input.next(), input.next(), input.next(),input.nextint());             }              catch(nosuchelementexception ee)             {                 system.out.println("error on input. please try again.");                 input.nextline();             }         }          output.close();     }     catch(exception e)     {         system.out.println("error working file");     } } }

thank help!

here's problem:

output.format("%s %s %s %s %d%n",input.next(), input.next(), input.next(), input.next(),input.nextint());

the calls read next tokens reading nothing, since earlier input.readline() has gobbled entire line. should using tokens[] object in formatter.

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...
