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

double pi = 4 * (1 - 1.0 / 3 + 1.0 / 5 - 1.0 / 7 + 1.0 / 9 - 1.0 / 11);
for (double i = 13; i <= 100000; i += 2)
    pi += Math.pow(-1, i / 2 + 1) / i;
System.out.println("Pi is " + pi);
