    Even sum: 192
    Odd numbers: 3
    Odd sum: 57

    and i have to read exactly 7 numbers from the user.
    i cant figure out how to get the sum for the even and odd numbers.
    this is what i have so far..
       import java.util.*;
       public class practiceLoops {
          public static void main ( String args[] )
          {
             Scanner scan = new Scanner (System.in);
     
             int even = 0;
             int sumE = 0;
             int odd = 0;
             int sumO = 0;
             int g = 1;
             int number = scan.nextInt();
     
             while ( g <= 6)
             {
     
                if ( number % 2 == 0)
                   even++;
                if (number % 2 == 1)
                   odd++;
     
     
                g++;
                number = scan.nextInt();		
             }
             System.out.printf ("even number: %d \n" +
                					"Even sum: %d \n" +
                					"odd numbers %d \n" +
                					"Odd sum %d", even, sumE, odd, sumO); 
     
     
          }
       }

    how to get the sum for the even and odd numbers.
    Add the number to the sum for that type of number:
    If the number is even, add to sumOfEvens
    if odd, add to sumOfOdds
    If you don't understand my answer, don't ignore it, ask a question.
