Question

我不知道如何编写main（）类来测试该程序。

我应该呼叫哪个构造函数来启动此纸牌游戏？哪个变量

这是我第一次在OO编程中运行，我设法获得了我需要的所有构造函数和方法。如何编写main()函数以运行所有代码？

public SimpaticoGame(DeckOfCards aDeck){
    aDeck.shuffle();

    DeckOfCards[] startingDecks = aDeck.dealCards(9);

    playerDeck = startingDecks[0];
    computerDeck = startingDecks[1];     

    playerHand = new StandardHand();
    computerHand = new StandardHand();

    playerWonLastRound = false;
}




/**
 * Plays a round of the Simpactico card game, flipping each of the top cards and
 * adding the cards to the winner's deck.
 */
public void playRound()
{
    try{
        playerLastCard = playerDeck.drawCard();
        computerLastCard = computerDeck.drawCard();

        playerHand.add(playerLastCard);
        computerHand.add(computerLastCard);    

    }
    catch (OutOfCardsException e) {
        //Game is over.
        return;
    }

    if(playerLastCard.compareTo(computerLastCard) == -1){
           computerDeck.add(playerHand);
           computerDeck.add(computerHand);
           playerHand = new StandardHand();
           computerHand = new StandardHand();
           playerWonLastRound = false;
        }

     if(playerLastCard.compareTo(computerLastCard) == 1) {
            playerDeck.add(playerHand);
            playerDeck.add(computerHand);
            playerWonLastRound = true;               
        }

     if(playerLastCard.compareTo(computerLastCard) == 0){
            try{
                playerLastCard = playerDeck.drawCard();
                computerLastCard = computerDeck.drawCard();

                playerHand.add(playerDeck.drawCard());
                computerHand.add(computerDeck.drawCard());

                playRound();
            }
            catch (OutOfCardsException e) 
            {
                //Game is over.
                return;
            }
        }
    }

Answer 1

public static void main(String[]args){
DeckOfCards aDeck = new DeckOfCards(); //or whatever your DeckOfCards constructor looks like

SimpaticoGame thisGame = new SimpaticoGame(aDeck);
//creating a new instance of the game! whatever is in your constructor will happen

thisGame.playRound(); //round will be played

}

Answer 2

不确定我是否了解，但是您可以尝试：

public class Main {

    public static void main(String[] args) {
        playRound();
    }

}

Answer 3

由于您的示例中缺少mroe类，因此我尝试了您的代码，但未编译。

但是与此同时，Java中的main方法如下：

public static void main(String... args) {

        // Code you want to execute first
        playRound(); // For example

}

只需将该方法放入您想要的任何类中，然后在其中添加一些逻辑并执行文件即可。如果您使用的是Eclipse和Netbeans之类的IDE，只需右键单击编辑器，然后单击即可运行。

Answer 4

尝试将您的playRound（）方法作为静态类。

public static void playRound()

以您的主角为

public static void main(String [] args)
{
   playRound();
}

如何使main（）运行此文件？
