Write a program to calculate the result of the formula pi in java 𝜋=4(1−1/3+1/5−1/7+1/9−1/11+1/13−⋯−1/2𝑖−1+1/2𝑖+1) with 10000 ≤ i ≤ 100000

import java.io.*;
public class Pi {
  public static void main(String[] args) {
    double pi = 0;
    for (int i = 10000; i <= 100000; i++) {
      if (i % 2 == 0) {
        pi -= (double) 1 / i;
      } else {
        pi += (double) 1 / i;
      }
    }
    pi = 4 * pi;
    System.out.println("Pi = " + pi);
  }
}
