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

public class Test {
    public static void main(String[] args) {
        double sum = 0.0;
        for (int i = 10000; i <= 100000; i++) {
            sum = sum + (1 / (2 * i - 1)) - (1 / (2 * i + 1));
        }
        System.out.println(4 * sum);
    }
}
