IsFlush boolean

I have this method IsFlush

that checks if the card is flush. I also have another method SuitHist

that creates a histogram of how many Suits are in the hand. The goal IsFlush

is to count the Suits in the array, and if 5 or more Suits are the same, return true. However, when I try to initialize SuitHist

to an Integer array flush

, the SuitHist parameter gives an error, any help I can get with this?

    public static int[] SuitHist(Card[] hand) {
        int[] histSuit = new int[4];
        for (int i = 0; i < hand.length; i++) {
        return histSuit;

    public static boolean IsFlush(Cards[] deck) {
        int[] flush = SuitHist(deck);
        for (int i = 0; i < flush.length; i++) {
            for (i = 0; i < 4; i++) {
                if (flush[i] >= 5)
                    return true;
        return false;

I think you have a typo. SuitHist

expects an array of type Card[]

, but in IsFlush

you have a deck of type Cards[]

. Try changing the function like this:

public static boolean IsFlush(Card[] deck){
