    Default What's wrong with my code? Card Program.

    Hey guys. Run into a small problem on a lab exercise. Supposed to use the method "dealACard()" inside of "dealAHand(int handSize)" Here's my actual instructions.

    "6. The dealACard method returns the Card from the array of Card objects in position nextCard. See the diagram below that illustrates how this should work.

    7. The dealAHand method has a loop that deals one Card (using the previous method) at a time until it has dealt handSize Cards. The String returned is a list of the Card objects in the hand similar to the result of toString except that the String returned here contains only handSize lines."

    I've attached my code, clearly I can't get the method "dealAHand(int handSize) to work, so I'm just leaving it blank. It does have to return on a String. Thanks for the help! The method I need help with, is the bottom one. Thanks!

    Default Re: What's wrong with my code? Card Program.

    where do the cards go as they are dealt?
    Call the dealACard() method once for each card that should be dealt to the hand.
    If you don't understand my answer, don't ignore it, ask a question.
