Question

I am trying to get a program to work but there are a couple of compile errors that I cannot figure out. Could you fix them so the program can run and compile properly. Thank you!

Explanation / Answer

Hi Sir, couple of updates are required in this program:-

1. Make sure you have the following 3 classes in the same working directory in different Java files - blackjack6.java, DeckOfCards.java, Card.java [each of them should be in its own class file]

2. In blackjack6.java, make sure the images that you have mentioned, 1.png, b1fv.png, etc should be in the same folder where the java classes are there as its unable to locate these images when launch(args) executes.

3. In DeckOfCards.java, the nextCard() method creates new Card object and return it

return new Card(this.deck[this.next_card++]);

Make sure the Card class has this constructor provided with valid args passed to it.

Let me know in case of any clarifications required. Thanks!
