public class CheckMyNumber {

    public static void main(String[] args) {

        boolean even = false;
        boolean prime = true;
        int myNumber = Integer.parseInt(args[0].trim());

• Even number
• An even number is an integer which is a multiple of two. If it is divided by two the result is another integer. Zero is an even number because zero multiplied by two is zero
• Odd number
• An odd number is an integer of the form n=2k+1, where k is an integer. Odd numbers leave a remainder of 1 when divided by two.
• Prime number
• A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.
