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 Main {
    public static void main(String[] args) {
        double pi = 4.0;
        boolean plus = false;
        for (int i = 3; i <= 100000; i += 2) {
            if (plus) {
                pi += 4.0 / i;
            } else {
                pi -= 4.0 / i;
            }
            plus = !plus;
        }
        System.out.println("pi=" + pi);
    }
}
