Write a program to find Number is a Odd or Even from 1 to N using while loop.
  import java.util.Scanner;
public class EvenOdd 
{
	public static void main(String[] args) 
	{
		Scanner scan = new java.util.Scanner(System.in);
		System.out.println("Enter the N: ");
		int n=scan.nextInt();
		int i=1;
		//condition used to identify number is odd or even
		System.out.println("Even Numbers:");
		while(i<=n)	
		{
			if(i%2==0)
			{
				System.out.println(i);
			}
			i++;
		}
		System.out.println("Odd Numbers:");
		i=1;
		while(i<=n)	
		{
			if(i%2!=0)
			{
				System.out.println(i);
			}
			i++;
		}
    }
