Prime Number Generator Logic

Question

I am supposed to make a class PrimeNumberGenerator which has a method nextPrime that will print out all prime numbers up to a number the user input

Answer 1

public class PrimeNumberGeneration {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    Scanner scan = new Scanner(System.in);
    int n = scan.nextInt();

    ArrayList primeNumbers = new ArrayList();
    primeNumbers.add(2);
    System.out.println(2);

    no_loop:
    for(int no=3; no<=n; no+=2){
        for(Integer primeNumber: primeNumbers){
            if((no%primeNumber)==0){
                continue no_loop;
            }
        }
        primeNumbers.add(no);
        System.out.println(no);
    }

}

}
