我的循环再运行一遍，我看不出为什么

Question

我有一个剪刀石头布游戏，该游戏应该一直运行，直到一名玩家获得4连胜。 一切似乎都可以正常运行，但是当一名玩家获得了连续4场胜利时，游戏就会多运行一次，我不知道为什么。

//当声明

while(!done){       
    done=play1Win.consecutiveWins==4||play2Win.consecutiveWins==4;
    player1Roll=random();
    player2Roll=random();

//这个草稿都在循环中，但是我只会张贴它的一部分。 全部都是一样

        if(player1Roll==SCISSORS&&player2Roll==PAPER){
        System.out.println("Scissors beats Paper! Player 1 wins");      
        lastWinner=PLAYER1;

        if (lastWinner==PLAYER1){
        play1Win.consecutiveWins++;
        play2Win.consecutiveWins=0;
        }
    }
    if(player1Roll==PAPER&&player2Roll==ROCK){
        System.out.println("Paper beats Rock! Player 1 wins");      
        lastWinner=PLAYER1;

        if (lastWinner==PLAYER1){
        play1Win.consecutiveWins++;
        play2Win.consecutiveWins=0;
        }

//这是循环的尽头

      System.out.println("Player 1 wins- " +play1Win.consecutiveWins );  
      System.out.println("Player 2 wins- " +play2Win.consecutiveWins);

输出是这样的：

    Paper beats Rock! Player 2 wins
    Player 1 wins- 0
    Player 2 wins- 1
    Paper beats Spock! Player 2 wins
    Player 1 wins- 0
    Player 2 wins- 2
    Rock beats Scissors! Player 2 wins
    Player 1 wins- 0
    Player 2 wins- 3
    Rock beats Scissors! Player 2 wins
    Player 1 wins- 0
    Player 2 wins- 4     // SHOULD STOP HERE
    Paper beats Rock! Player 1 wins    
    Player 1 wins- 1
    Player 2 wins- 0

如果有人能指出我正确的方向，那就太好了。 谢谢！

Answer 1

您应该将此行放在while循环的最后一行

done=play1Win.consecutiveWins==4||play2Win.consecutiveWins==4;

Answer 2

您可以在循环开始时设置完成条件。 这意味着即使player2连续获得了4次胜利，在下一个循环开始之前，done都不会设置为true。 将此行移到while循环的末尾：

  done=play1Win.consecutiveWins==4||play2Win.consecutiveWins==4;

Answer 3

要在连续四次获胜后立即关闭循环，应在循环结束时而不是在NEXT循环开始时检查退出标准。 如果您在循环开始时检查退出条件，则将其作为您的一部分，就像重写while (!done){...}

至

while(play1Win.consecutiveWins==4||play2Win.consecutiveWins==4){ ... }
