class SumOfNEven
    public static void main(String args[])
       int i,j,N,sum=0;
       System.out.println("Enter The Value Of N");
       Scanner sc=new Scanner(;

            System.out.println("The Sum Of N Even Numbers: "+sum);

Program Explanation

1.    Get input N (How many even numbers to be summed)

2.     Instruction(s) inside the for block{} are executed repeatedly till the second expression (j<=N) is true.


3.    Here i is initialized to 2 and j is initialized to 1 and i is incremented by 2 and  j is incremented by 1 for each           iteration.

       instructions inside the for block are executed in every iteration and iteration stops when j becomes                       greater than N. so value of i (2,4,6... ) will be added to sum.

        so even numbers (i) are added to the sum for j --> 1 to N times

        sum = sum + j

        sum = 0 + 2

        sum = 2 + 4

        sum = 6 + 6

        sum = 12 + 8



        after adding all N even numbers to sum, sum will be printed using system.out.println().
