Why does this while loop iterate
If the char variable again is initialized to 'N' then why does this loop iterate the first time
import java.util.Scanner;
public class teest
{
public static void main (String[] args)
{
Scanner keyboard = new Scanner(System.in);
int num;
String input;
char again = 'N';
while(again == 'Y' || again == 'y')
{
System.out.println("enter num: ");
num = keyboard.nextInt();
System.out.println("The number entered was " + num);
System.out.println("Do it agian?");
keyboard.nextLine();
input = keyboard.nextLine();
again = input.charAt(0);
}
}
}
