How to implement a method to calculate the power of an Integer in Java

Answer 1

public class MyClass {
     static int calculatePower(int n, int power) {
        int result = 1;
        if (n > 0 && power == 0) {
            return result;
        }
        else if (n == 0 && power >= 1) {
            return 0;
        }
        else {
            for (int i = 1; i <= power; i++) {
                result = result * n;
            }
            return result;
        }
    }
    public static void main(String args[]) {
        int n = 2;
        int power = 4;

        System.out.println(calculatePower(n, power));
    }
}
