使用另一个类的方法

Question

I was given a class called PokerHand that creates a poker hand.

Now I want to use the same methods on a different class called fiveCardDraw to create a totally different poker hand for a dealer and a player so I created two arrays:

PokerHand [] dealer = new PokerHand[5];
PokerHand [] player = new PokerHand[5];

Where I am going to store the cards, but I want to use the methods on the Pokerhand class such as:

addCard()
getCards()

How can I called those methods into the fiveCardDraw class and store them into the arrays I created?

Answer 1

You can either call them from the objects that are of type PokerHand (my recommended method)

dealer[i].addCard();
player[i].getCards();

Or if they're applicable you can convert the methods to static and they'll be callable from PokerHand.addCard() .

MyClass obj = new MyClass();
obj.foo = PokerHand.addCard();

Answer 2

if they are static methods then you would put:

fiveCardDraw.addCard();

if they are not static then you would have to create and instance (or object) of the fiveCardDraw class ex:

fiveCardDraw cardDraw = new fiveCardDraw();

and then add

cardDraw.addCard();

Answer 3

what do you want is this?`

class fiveCardDraw {
private PokerHand [] player = new PokerHand[5];
private PokerHand [] dealer = new PokerHand[5]; 
pulic void addPlayerCard(PokerHand [] ph){
do something...
} 
pulic void addDealerCard(PokerHand [] ph){
do something...
} 
public PokerHand [] getPlayerCards()
return player;
}
public PokerHand [] getDealerCards()
return dealer;
}
