how to add numbers that are in an array so a highscore could be output

I need to find the sum of the ranks from 13 cards that a user is dealt.

this is in my class card.java which returns the value of the card as a string then the suit as a string and then the rank as an int.

public  String toString(){

String s = ("I am the " + rankString[rank-2] + " of " + suit + "(rank): " + rank);

    return  s;

}

this is in my CardFrame class. CardFrame.java

private void doButton1Stuff(){
    //textArea.append("\nButton 1 Clicked");
    textArea.setText("");
    for(int i = 0; i<13; i++){
    textArea.append(deck.getNextCard().toString()+"\n");
    }

everything is working fine i just need to figure out a way to add all the ranks together from the 13 cards the user is dealt and output that as their score. 

public Card getNextCard(){
    //check for end of deck
        topCard++;
        if(topCard==53){
        topCard = 1;
        shuffle();
        }


    return cards[deck[topCard-1]];

It looks like your "Card" class (I can't tell what you've named it from your code) has a "rank" member which I'm guess is an integer. So I think what you're having trouble with is the iteration. Try this:

private void doButton1Stuff(){
    //textArea.append("\nButton 1 Clicked");
    textArea.setText("");
    int score = 0;
    for(int i = 0; i<13; i++){
        Card card = deck.getNextCard();
        score += card.rank
        textArea.append(card.toString()+"\n");
    }
    textArea.append("Score: ");
    textArea.append(score);
}

This assumes that your member var "rank" is accessible (see "public", "protected", "private")

In case you cant access to your rank value from Card class you can always read it from its toString() output like this:

String cardToStringOutput = "I am the " + "rankString[rank-2]" + " of "
        + "suit" + "(rank): " + "11";
int rank=Integer.parseInt(cardToStringOutput.split(" ")[6]);
System.out.println("rank="+rank);

But consider to add some getter to Card class so you don't have to do use above code.

You'd need an accessor for your rank variable.

public int getRank() {
    return rank;
}

Then you can use it for every card in some collection (here I assume an array):

for(Card c: cards) {
    sum += c.getRank();
}

For your use case, it could be used here:

int sum = 0;
for(int i = 0; i<13; i++) {
    Card c = deck.getNextCard();
    textArea.append(c.toString()+"\n");
    sum += c.getRank();
}
