Thread: Can someone explain why my loop does not run again even when "y" is entered.

import java.util.Scanner;
public class EvenOrOdd
{
public static void main (String[]args)
{
String a = "y";
while (a.equals("y")){
Scanner stdin = new Scanner(System.in);
System.out.print("Enter a number:");
int x = stdin.nextInt();
if ( x % 2 == 0)
{
System.out.println(x + " is even ");
}
else if (x % 2 == 1)
{
System.out.println(x + " is odd ");
}
System.out.println("Enter y to play again, n to quit(y/n):");
a = stdin.next();
}
}

}

    public static void main (String[]args) {
        String a = "y";
        while (a.equalsIgnoreCase("y")) {
            Scanner stdin = new Scanner(System.in);
            System.out.print("Enter a number: ");
            int x = stdin.nextInt();
            System.out.println( x % 2 == 0 ? x + " is even" : x + " is odd");
            System.out.println("Enter y to play again, n to quit(y/n): ");
            a = stdin.nextLine();
        }
    }
