Prime Factorization in Java ?

import java.util.ArrayList;
import java.util.List;

public class PrimeFactorization {

public static List<Integer> primeFactors(int numbers) {
int n = numbers;
List<Integer> factors = new ArrayList<Integer>();
for (int i = 2; i <= n / i; i++) {
while (n % i == 0) {
factors.add(i);
n /= i;
}
}
if (n > 1) {
factors.add(n);
}
return factors;
}

public static void main(String[] args) {
for (Integer integer : primeFactors(44)) {
System.out.println(integer);
}

System.out.println("---------");

for (Integer integer : primeFactors(3)) {
System.out.println(integer);
}
}

}

Below is the Output....
