inputstream - Java Scanner doesn't read all the inputs -

i have input 1000002 lines. first line has 2 number n, q. there n number 1 n in next line , q lines after second line.

in input, n 100000 , q 1000000.

when try read inputs java code, paste stdin although last input copied, code doesn't reach end , seems didn't read inputs. here code:

import java.util.scanner; import java.util.list; import java.util.arraylist; import java.lang.*; import java.io.*;  public class test {     public static void main(string[] args) {         int n;         int q;         scanner s = new scanner(system.in);         n = s.nextint();         q = s.nextint();         (int = 0; < n; i++) {             int id = s.nextint();         }         for(int = 0; < q; i++) {             int nodex = s.nextint();             int nodey = s.nextint();         }         s.close();         system.out.println("done");     } } 

here input file 12 mb :) input.txt

also when try print know number of read inputs, last 950000.

so what's wrong this?
