when this code is run it just continues. It needs to stop at 21 Or then say bust.

Is someone able to help PLEASE :-)

import java.util.Scanner;

public class Pontoon{

    playerScore += dealCard();
    computerScore += dealCard();
    playerScore += dealCard();
    computerScore += dealCard();

    System.out.printf("Your score is %d would you like another card ? y/n ", playerScore);
    newCard = input.nextLine();
