Answer 1

Answer:

Explanation:

class SumOfNumbers

{

   public static void main(String arg[])

   {

       int input = 6;

       int sum = 0;

       

       for(int i = 1; i <= input; i++)

       {

           sum = sum + i;    // LINE A

           System.out.println("Sum after adding " + i + " is : " + sum);  

       }

       

       System.out.println();

       System.out.println("Sum of numbers till " + input + " is " + sum); // LINE B

   

   }

}

OUTPUT

Sum after adding 1 is : 1

Sum after adding 2 is : 3

Sum after adding 3 is : 6

Sum after adding 4 is : 10

Sum after adding 5 is : 15

Sum after adding 6 is : 21

Sum of numbers till 6 is 21
