Question

I cant figure out how to add the values after it spits out the numbers.
it says:

Number: 5 // I typed 5
1 2 3 4 5
The sum is.

So i need to add those number 1 2 3 4 5 but cant figure out how.

 import java.util.Scanner
 public class AddingValuesWithAForLoop
 {
      public static void main( String[] args )
      {
          Scanner keyboard = new Scanner(System.in);
          System.out.println( " \n" );

          System.out.println( "Number: " );
          int number = keyboard.nextInt();
          int sum = 0;

          for (int run=1; run<=number; run=run+1)
          {
              System.out.print( run + " " );
              sum = sum + 1 ;
          }

          System.out.println( "The sum is . " );
     }
 }

You need to add run to sum and then print it out, like this:

import java.util.Scanner

public class AddingValuesWithAForLoop
{
    public static void main( String[] args )
    {

        Scanner keyboard = new Scanner(System.in);
        System.out.println( " \n" );

        System.out.println( "Number: " );
        int number = keyboard.nextInt();
        int sum = 0;

        for (int run=1; run<=number; run=run+1)
        {
            System.out.print( run + " " );
            sum = sum + run; 
        }

        System.out.println( "The sum is " + sum );

    }
}
