How to find the numbers that are the sum of fifth powers of their digits in Java

Answer 1

public class FifthPowerSumFinder {

    // Calculates the sum of the fifth powers of the digits of a number
    private static int sumOfFifthPowers(int n) {
        int sum = 0;
        int temp = n;

        while (temp > 0) {
            int digit = temp % 10;
            sum += digit * digit * digit * digit * digit;
            temp /= 10;
        }

        return sum;
    }

    public static void main(String[] args) {
        for (int i = 1000; i < 1_000_000; i++) {
            if (i == sumOfFifthPowers(i)) {
                System.out.println(i);
            }
        }
    }
}
