Java Display the Prime Factorization of a number

Question

So for my assignment, I have to write a program that asks the user for an integer input and then print out that number\'s prime factorization. This is what I have:

Answer 1

Not sure why you are printing the multiplication twice! Here is the cleaned up code:

public static void printPrimeNumbers(int prime) {

    int n;

    for (int i = 2; i <= prime; i++) {
        n = 0;
        while (prime % i == 0) {
            prime /= i;
            n++;

        }

        if (n != 0) {
            for (int j = n; j > 0; j--) {
                System.out.print(i);

                if (prime != 1) {
                    System.out.print("*");
                }
            }
        }
    }
}
