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.lang.Math;

public class pi{
    public static void main(String[] args){
        int i = 0;
        double pi = 0;
        for(i=10000; i<=100000; i+=2){
            pi += (1/(2*i-1) - 1/(2*i+1));
        }
        pi *= 4;
        System.out.println(Math.PI+"\n"+pi+"\n"+Math.PI-pi);
    }
}
