For Loop

For Loop

Write a program using a for loop that computes the following sum:

1/2 + 2/2 + 3/2 + 4/2 + 5/2 + ... N/2

N will be an integer limit the user enters.

This is an example of my upcoming quiz. I need help on knowing the answer to this to be sure to pass my quiz.

import java.util.*;
class SumOfSeries
{
    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.print("Enter the value of n: ");
        int n=input.nextInt();
        int sum=0;
        //1/2 + 2/2 + 3/2 + 4/2 + 5/2 + ... N/2
        for(int i=1;i<=n;i++){
            sum+=i;
        }
        int sumOfSeries=1/2*(sum);
        System.out.println("Sum of series: "+sum);
    }
