How to calculate the sum of digits of 2 power 15 in Java

Answer 1

public class MyClass {
    private static int sumDigits(int num) {
    	int sum = 0;
    	
    	while (num != 0) {
    		sum += num % 10;
    		num /= 10;
    	}
    
    	return sum;
    }
    public static void main(String args[]) {
        int base = 2;
	    int exponent = 15;

	    int power = (int)Math.pow(base, exponent); // 32768

	    System.out.print(sumDigits(power));
    }
}
