Program or Solution


Program Explanation

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

Here i is initialized to 2 and incremented by 2 for each iteration, instructions inside the for block are executed unless i becomes greater than n.

so value of i (1,3,5...n)will be added to sum.

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