Java Even Odd Integer adding Yes or No question to play again

I am very new to Java and struggling to complete an assignment. I have read several posts but can't seem to figure out how to add the "Enter·y·to·play·again,·n·to·quit(y/n)" into my code. Here is what i have so far. Any direction would be appreciated. I can't figure out how to get it to return to Enter one number. THX //Program to display Even or Odd Integer

public class EvenOdd {
    public static void main(String[] args) { //method to determine is a number is even or odd
        Scanner input = new Scanner(System.in);
                int number; //number o be entered
        System.out.print("Enter one number: "); //prompt user to enter a number
        number = input.nextInt();
                  switch (number % 2) {
            case 0:
              System.out.printf("%d is even\n", number);
            case 1:
              System.out.printf("%d is odd\n", number);
          }
            System.out.print("Enter Y to play again, N to quit: "); //prompt user to enter a number
            number = input.nextInt();
        }
    public boolean isEven(int number) {
    return number %2 == 0;
    } //end method isEven
    } //end class EvenOdd```

Result:
Enter one number: 1
1 is odd
Enter Y to play again, N to quit: n
