and code form main method:

file orderdata = new file("purchaseorderdata.txt");             scanner datascan = new scanner(orderdata);  while(datascan.hasnextline()) {     string linedata = datascan.nextline();      scanner linescan = new scanner(linedata);     linescan.usedelimiter("#");      string date = linescan.next(); // line 259     string id = linescan.next();     string code = linescan.next();      string quantityplus = linescan.next();      if(!quantityplus.contains("@"))         management.addnewpurchaseorder(date, id, code,                                      integer.parseint(quantityplus)); // line 267     else     {         quantityplus = quantityplus.replace("@", "");         management.addnewpurchaseorder(date, id, code,                                     integer.parseint(quantityplus));         management.startnewmonth();     }

on first instance of 

management.addnewpurchaseorder(date, id, code, integer.parseint(quantityplus));

i exception:

java.lang.numberformatexception: input string: "2 "     @ java.lang.numberformatexception.forinputstring(numberformatexception.java:65)     @ java.lang.integer.parseint(integer.java:580)     @ java.lang.integer.parseint(integer.java:615)     @ assignment2.maintest.main(maintest.java:267)

if do:

string quantityplus = linescan.next(); quantityplus = quantityplus.replace(" ", "");

i following:

java.util.nosuchelementexception java.util.nosuchelementexception     @ java.util.scanner.throwfor(scanner.java:862)     @ java.util.scanner.next(scanner.java:1371)     @ assignment2.maintest.main(maintest.java:259)

maintest.java:259 - string date = linescan.next();

i've tried use nextint() well, result same. wrong there?

thanks lot!

maintest.java:259 - string date = linescan.next(); should check before if line not empty might why scanner throwing exception
