为什么这总是发现它们都是真的？

Question

public class GameLauncher {

    public static void main(String[] args) {
        GuessGame game = new GuessGame();
        game.startGame();
    }
}

public class Player {
    int number = 0;

    public void guess() {
        number = (int) (Math.random() * 10);
        System.out.println("I'm guessing " + number);
    }
}

public class GuessGame {


    public void startGame() {
        Player p1 = new Player();
        Player p2 = new Player();
        Player p3 = new Player();

        int guessp1 = 0;
        int guessp2 = 0;
        int guessp3 = 0;

        boolean p1isRight = false;
        boolean p2isRight = false;
        boolean p3isRight = false;

        int targetNumber = (int) (Math.random() * 10);
        System.out.println("I'm Thinking of a number between 1 and 10");

        while (true) {
            System.out.println("Number to guess is " + targetNumber);

            p1.guess();
            p2.guess();
            p3.guess();

            guessp1 = p1.number;
            System.out.println("Player one guessed " + guessp1);

            guessp2 = p2.number;
            System.out.println("Player two guessed " + guessp2);

            guessp3 = p3.number;
            System.out.println("Player three guessed " + guessp3);

            if (guessp1 == targetNumber) {

                p1isRight = true;
            }

            if (guessp2 == targetNumber) {
                p2isRight = true;
            }

            if (guessp3 == targetNumber) {
                p3isRight = true;
            }

            if (p1isRight || p2isRight || p3isRight) {
                System.out.println("We have a winner!");
                System.out.println("Was player one correct? "
                + p1isRight);
                System.out.println("Was player two correct? "
                + p2isRight);
                System.out.println("Was player three correct? "
                    + p3isRight);
                } else {
                    System.out.println("None them players were correct man.");
                }

            }
        }
}

好的，我已经检查了很多次，但是每次运行它时，它都会显示所有播放器都是正确的？即使在它清楚地打印出玩家猜测的实际数字之前，它们也不是真的。

Answer 1

您忘记在每次循环后将三个 isRight 变量重置为 false。

所以他们在之前的运行中保持true。

Answer 2

改变

if (guessp1 == targetNumber) {
    p1isRight = true;
}

if (guessp2 == targetNumber) {
    p2isRight = true;
}

if (guessp3 == targetNumber) {
    p3isRight = true;
}

到

p1isRight = guessp1 == targetNumber;
p2isRight = guessp2 == targetNumber;
p3isRight = guessp3 == targetNumber;

按照您当前代码的方式，当您再次执行循环时，您永远不会覆盖“真”值。
