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

Try this code to generate prime number series

public class prime1 {

public static void main(String[] args) {

    int max = 100;

    System.out.println("Generate Prime numbers between 1 and " + max);

    // loop through the numbers one by one
    for (int i = 1; i < max; i++) {

        boolean isPrimeNumber = true;

        // check to see if the number is prime
        for (int j = 2; j < i; j++) {
            if (i % j == 0) {
                isPrimeNumber = false;
                break; // exit the inner for loop
            }
        }

        // print the number if prime
        if (isPrimeNumber) {
            System.out.print(i + " ");
        }
    }

}

}
