【问题描述】：
我正在尝试正确结束此游戏，但 do while 循环或我正在执行的操作导致游戏继续进行。如果有人有进一步的建议让我在任一得分达到 99 后结束这场比赛，我将不胜感激。我已经粘贴了这两个类的来源。我也是学生，请见谅。
类
package programming2;

import java.util.Scanner;
public class Matador {
public static void main(String[] args) {
/*The game is played between the player and the computer.
The player's score and the computer's score each begin at 0.

System.out.println("Values for 1st dice is: " + matador.getValueDie1() + " and " + matador.getValueDie2());
System.out.println("Combined values are " + matador.getValue());
turn = 0; // start of loop marker for player 1

// turn changes and also end of loop marker

System.out.println("Player 1 final score is: " + playerScore + " |-| player 2 final score is " + computerScore);

while (playerScore < 98 || computerScore <98 || quit != 1);

while (playerScore < 98 || computerScore < 98 || quit != 1); // end of master loop
System.out.println("Player 1 final score is: " + playerScore + " |-| player 2 final score is " + computerScore);
}
}
如果需要其他类，但它与分数无关，因为它主要用于确定一些值：
package programming2;
import java.util.Random;
import java.util.Scanner;
public class Die {
private int die1; //instance variable
private int die2;
private int rolledDice;
public Die() { //constructor assigns random value
die1 = (int) (Math.random()*6)+1;
die2 = (int) (Math.random()*6)+1;
}
public void rollDieNow () { //rolls dice
Random randGen = new Random();
die1 = randGen.nextInt(6) + 1;
die2 = randGen.nextInt(6) + 1;
}
public int getValue() { // gets dice value
rolledDice = die1 + die2;
return rolledDice;
}
public int getValueDie1() { // gets die1 value
return die1;
}
public int getValueDie2() { // gets die2 value
return die2;
}
}
【问题讨论】：
-
这个条件是什么意思：
turn < turn + 1? -
while (playerScore < 98 || computerScore < 98 || quit != 1)|| 应该是&&。只要满足所有这些条件，而不是至少满足其中一个条件，您就希望运行循环。目前，您的循环只会在playerScore >= 98和computerScore >=98和quit==1时停止。但只要达到其中一个条件就应该标志着游戏的结束。 -
我使用变量 turn 来确定玩家何时结束，如您所见的 if 条件。在某些情况下回合增加回合丢失，所以我使用 break 来打破循环并让其他玩家选择。
