Near-complete Program

Here is the program, except for a blank or two:

import java.io.*;
import java.util.Scanner;
class AddUpAll
{
  public static void main ( String[] args ) throws IOException
  {
    int value;             // the value of the current integer
    int limit;             // the number of integers to add up
    int sum = ; // initialize sum
    
    // Prompt for and open the input file   
    Scanner user = new Scanner( System.in );
    System.out.print("File name? ");
    String fileName = user.next().trim();
    Scanner scan = new Scanner( new File(fileName) );  // Note how this is done.

    // get the number of integers to add up
    limit = scan.nextInt();
    int count = ;   // initialize count

    while ( count <=  )
    {
      value  = scan.nextInt();
      sum    = ;   // add to the sum
      count  = ;   // increment count
    }

    System.out.println( "Grand Total: " + sum );
  }
}
