Nested if-else Statement

Here is the not-quite finished program:

import java.io.*;

// User enters a value N
// Add up odd integers,  even  integers, and all integers 0 to N
//
class addUpIntegers
{
  public static void main (String[] args ) throws IOException
  {
    BufferedReader userin = new BufferedReader (new InputStreamReader(System.in));
    String inputData;
    int    N, sumAll = 0, sumEven = 0, sumOdd = 0;

    System.out.println( "Enter limit value:" );
    inputData = userin.readLine();
    N         = Integer.parseInt( inputData );

    int count = 0 ;
    while (  count <= N )    
    {
      sumAll = ______________ ;
      
      if ( ______________  )
        sumEven = ______________ ;

      else
        sumOdd = ______________ ;

      count = count + 1 ;
    }

    System.out.print  ( "Sum of all : " + sumAll  );
    System.out.print  ( "\tSum of even: " + sumEven );
    System.out.println( "\tSum of odd : " + sumOdd  );
  }
}

The loop body in this program contains an if statement. This is fine. An if statement inside of a loop body is called a nested if. There is nothing special about it; it works just as it would outside of the loop body.
