java - Finding smallest and largest population and the average -

i've been working on getting program work. i'm having little trouble getting program read files have created, census2000 , census2010. these contain 50 states , population in 2000 , 2010. believe rest of program correct. told use methods find smallest population, largest population , average. here 2 lines 2000 file:

alabama 4447100

alaska 626932

here program:

public static void main(string[] args) throws ioexception {         string state = "";         int population = 0;         int p = 0, s = 0, pop = 0, stat = 0, populate = 0, sum = 0;         file f = new file("census2000.txt");         scanner infile = new scanner(f);         infile.usedelimiter("[\t|,|\n|\r]+");         while (infile.hasnext()) {             checksmall(p, s);             checklargest(pop, stat);             checkaverage(populate, sum);             population = infile.nextint();             state = infile.next("/t");             system.out.println(state + "has" + population + "people");         }          system.out.println(state + "has smallest population of" + population);         prw.close();     }      public static boolean checksmall(int p, int s) {         boolean returnvalue;         if (p < s) {             returnvalue = true;         } else {             returnvalue = false;         }         return (returnvalue);     }      public static boolean checklargest(int pop, int stat) {         boolean returnval;         if (pop > stat) {             returnval = true;         } else {             returnval = false;         }         return (returnval);     }      public static int checkaverage(int populate, int sum) {         int retval;         retval = populate + sum;         return (retval);     }       } 

what doing wrong?

i believe problem here:

state = infile.next("/t"); 

i think you're trying skip tab in file , read state? reading in line , splitting line using \t delimiter.

string line; while (infile.hasnextline()){     line = infile.nextline();     string data[] = line.split("\\s+");     state = data[0];     population = integer.parseint(data[1]); } 

edit: other answer points out, you're attempting perform functions on file's data before it's read.
