Question

如果玩家在我的硬币投掷游戏中赢了或输了，我试图获得正确的输出。游戏翻转一个虚拟硬币100次，如果玩家选择了翻转获胜最多的硬币，如果少，那么他们选择的硬币将丢失。但输出总是错误的。

public class Strategy extends Object {

        /**
         * 
         * Encoding for a strategy.
         */

        int opponentLastMove = 1;

        int myLastMove = 1;

        String name;

        // 0 = defect, 1 = cooperate

        public Strategy()

        {

        } /* Strategy */

        public int nextMove()

        {

            return 0;

        } /* nextMove */

        public void saveOpponentMove(int move) {
            opponentLastMove = move;
        }

        public int getOpponentLastMove() {
            return opponentLastMove;
        }

        public void saveMyMove(int move) {
            myLastMove = move;
        }

        public int getMyLastMove() {
            return myLastMove;
        }

        public String getName() {
            return name;
        }

    }

public class StrategyRandom extends Strategy

{

    /**
     * 
     * Encoding for a strategy.
     */

    // 0 = defect, 1 = cooperate

    public StrategyRandom()

    {

        name = "Random";

    } /* StrategyRandom */

    public int nextMove()

    {

        if (Math.random() < 0.5)
            return 1;

        return 0;

    } /* nextMove */

}

                    + "\nPress 0 to Exit");
            choice = Integer.parseInt(scanner.nextLine());

                System.out.print("\nHello " + stratRandom.getName()

        } catch (Exception ex) {

            ex.printStackTrace();

        }

    }

这条线似乎是你的问题。您正在测试最后一次硬币翻转是赢还是输，而不是谁的总金额更高。

if (coinFlip == 1) {
     System.out.println("\nYou Won");
} else {
     System.out.print("\nYou Lost");
            }

将其更改为

if( choice == 1 ){
    if (heads > tails)
         System.out.println("\nYou Won");
    else if(tails > heads )
         System.out.print("\nYou Lost");
}else{

    if ( heads < tails ) 
        System.out.println("\nYou Won");
    else if( tails < heads )
        System.out.print("\nYou Lost");
}
if( heads == tails )
    System.out.println(\n"It is a tie!");

如果玩家在掷硬币时赢了或输了，输出错误
