java - Reading from a text file into an array -

hi im trying hackerearth challenge sum of medians , involves me reading text file , storing values in array. first value has stored in variable n able the remaining values have stored in array. become stuck. have read each value line line , store in array . code have been trying working on cant see im going wrong.

import java.io.bufferedreader;  import java.io.inputstreamreader;   class testclass {   public static void main(string args[] ) throws exception {    // read number of data system standard input.   bufferedreader br = new bufferedreader(new inputstreamreader(system.in));   string line = br.readline();   int n = integer.parseint(line);   int = 1;  int[] myintarray = new int[n];   // median sum   long summedians = 0;   int median = 0;    while (i<n)       //read 1 line file , parse integer      //store value in array  {        myintarray [i] = integer.parseint(line);   = + 1; // increment total numbers read  } 

so said must increment through text file storing each value on line in array. amazing

the text file

5

10

5

1

2

15

one string per line, have pass integer. doing after store value line array sorting , finding medium , repeat process until values text file have been read.

the problem trying 1

if you're reading text file (and not standard input you're doing @ moment) want like:

// warning: fail if filename invaild. bufferedreader br = new bufferedreader(new filereader("inputfilename.txt")); 

to read in each line, can use following in while loop:

// warning: crash program if line contains other integers. myintarray[i] = integer.parseint(br.readline())  = + 1; // increment total numbers read 

you should close reader @ end:

try{   br.close(); } catch (ioexception e) {   system.out.println("error, program exit!");   system.exit(1); } 

the import should swapped import java.io.inputstreamreader to: import java.io.filereader
