如果玩家在抛硬币时赢了或输了，输出错误

Question

如果玩家在我的抛硬币游戏中赢了或输了，我试图得到正确的输出。游戏将一枚虚拟硬币抛100次，如果玩家选择的硬币被抛次数最多的那枚获胜，如果次数较少，那么他们选择的硬币将会失败。但是输出总是出错。

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;
        }

            return name;

    }

    {
        name = "Random";
    } /* StrategyRandom */
    public int nextMove()
    {
        if (Math.random() < 0.5)
            return 1;

这一行似乎是您的问题。你是在测试最后一次抛硬币是赢还是输，而不是测试谁的总金额更高。

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

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!");
