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

you can also get some help from the below function.

public int getPrimeNumber(double number) {
    int j = 0;
    while (number % 2 == 0) {
        number = number / 2;
        j = 2;
    }

    for (int i = 3; i <= number; i = i + 2) {
        while (number % i == 0) {
            number = number / i;
            j = i;
        }
    }

    return j == 0 ? 1 : j;
}

This function will return the largest prime factor of the given number.
