java - for loop filling array[0] but thats it -

the aim of loop create new currentjob each line of text file , store in array. loop stores first line of text doesn't store else.

public static void job() { file file = new file("dailyjobs.txt"); seek { scanner scanner = new scanner(file); while(scanner.hasnextline()) { string line = scanner.nextline(); scanner linescanner = new scanner(line); linescanner.usedelimiter(","); job[] jobarray = new job[30]; (int = 0; < jobarray.length; i++) { job currentjob = new job(); int jid = linescanner.nextint(); int cid = linescanner.nextint(); string rego = linescanner.next(); string date = linescanner.next(); string day = linescanner.next(); double fee = linescanner.nextdouble(); int[] sc = new int[4]; int f = 0; while(linescanner.hasnextint()) { linescanner.usedelimiter(","); sc[f] = (linescanner.nextint()); f++; } currentjob.setjobid(jid); currentjob.setcustomerid(cid); currentjob.setregistration(rego); currentjob.setdate(date); currentjob.setday(day); currentjob.settotalfee(fee); currentjob.setservicecode(sc); jobarray[i] = currentjob; system.out.println(currentjob.getjobid()); system.out.println(currentjob.getcustomerid()); system.out.println(currentjob.getregistration()); system.out.println(currentjob.getdate()); system.out.println(currentjob.getday()); system.out.println(currentjob.gettotalfee()); system.out.println(arrays.tostring(currentjob.getservicecode())); system.out.println(arrays.tostring(jobarray)); } } }catch (exception e) { } } }

`` i'm getting @ moment

90301 14304 itguru 11/11/2014 tuesday 735.75 [1204, 1205, 0, 0] [job@1c31e2ad, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null]

90301 downwards [1204, 1205, 0, 0] contents of line. can see it's storing first line of text file , nothing. need help prepare this.

completely forgot grab statement beingness empty yes it's showing issues

you mentioned exception nosuchelementexception occures here:

int jid = linescanner.nextint();

this means, scanner tries read int, not there. main problem current code structure:

int jid = linescanner.nextint(); int cid = linescanner.nextint(); string rego = linescanner.next(); string date = linescanner.next(); string day = linescanner.next(); double fee = linescanner.nextdouble(); // omitted code while(linescanner.hasnextint()) { linescanner.usedelimiter(","); sc[f] = (linescanner.nextint()); f++; }

you're reading stuff , assigning variables, you're reading until lastly integer (linescanner.hasnextint()). loop stop if there no more integer read available. after that, you're doing more stuff not necessary here.

this first iteration of for (int = 0; < jobarray.length; i++). comes next iteration. linescanner still same, hence there integer read due loop while(linescanner.hasnextint()), sec iteration reach line int jid = linescanner.nextint();. scanner tries read int, can't find read , throws nosuchelementexception.

to prepare that, should reset linescanner read new line. or delete for loop, because while(scanner.hasnextline()) take care of reading each available line , linescanner "filled" correctly. , please re-think current position of variable job[] jobarray = new job[30];. you'll lost info on each new line of file.
