Print sum of series 1/1^3 – 1/2^3 + 1/3^3…….1/n^3 in Java.

import java.util.Scanner;
public class  Series 
{
 public static void main(String[] args) 
 {
  Scanner sc = new Scanner(System.in);
  double sum = 0;
  System.out.println("Enter the no of terms ");
  int n = sc.nextInt();
  for (int i = 1; i <= n; i++) 
  {
   if (i % 2 == 0) {
    sum = sum - (double) 1 / (i * i * i);
   } else {
    sum = sum + (double) 1 / (i * i * i);
   }
  }
  System.out.println(" Sum of the series : " + sum);
 }
}

Output:

Enter the no of terms
