Write a program in Java to accept a number. Check and print whether it is a prime number or not.

A prime number is a number which is divisible by 1 and itself only. For example 2, 3, 5, 7, 11, 13 are all prime numbers.

import java.util.Scanner;

public class KboatPrimeCheck
{
    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter number: ");
        int n = in.nextInt();
        int c = 0;

        for (int i = 1; i <= n; i++) {
            if (n % i == 0) {
                c++;
            }
        }

        if (c == 2) {
            System.out.println(n + " is a prime number");
        }
        else {
            System.out.println(n + " is not a prime number");
        }
    }
}
