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 Pi {
    public static void main(String[] args) {
        double pi = 0.0;
        System.out.println("i                  m(i)");
        System.out.println("-----------------------");
        for (int i = 10000; i <= 100000; i += 10000) {
            pi = 0.0;
            for (int j = 1; j <= i; j++) {
                if (j % 2 == 0) {
                    pi += 1.0 / (2 * j - 1);
                } else {
                    pi -= 1.0 / (2 * j - 1);
                }
            }
            pi *= 4.0;
            System.out.printf("%d\t\t%10.4f\n", i, pi);
        }
    }
