Prime factorization of Java display numbers

Therefore, for my task, I must write a program that requires the user to input an integer, and then print out the prime factorization of the number

import java.util.Scanner;

public class PrimeFactor {
    public static void main(String[] args) {
        System.out.print("Enter a positive number: ");
        Scanner scanner = new Scanner (system.in);
        int number = scanner.nextInt();
        int count;
        for (int i = 2; i<=(number); i++) {
            count = 0;
            while (number % i == 0) {
                number /= i;
                count++;
                if (count == 0) {
                    continue;
                }
            }
            System.out.println(i+ "**" + count);
        }
    }
}

The problem I'm facing now is that whenever I run it, such as 15453, I get a list of each factor from 1 to 100 and its index. When I just think about the factor factor factor, I'm trapped in how to continue

Solution

You're almost there! Move the if - continue block out of the for loop Otherwise, it will "continue" the innermost loop, not the loop you want

while (number % i == 0) {
    number /= i;
    count++;
}
if (count == 0) {
    continue;
}
System.out.println(i+ "**" + count);

Alternatively, you can include system. In if (count! = 0) out. Println is called because it is the only statement to continue:

while (number % i == 0) {
    number /= i;
    count++;
}
if (count != 0) {
    System.out.println(i+ "**" + count);
}
