Question

我不知道这会不断重复“最后一个迷路的人”。我想尝试使该游戏重复3次，以便玩家可以重复3次，但不会重复。另外，当我尝试输入if（enter！= 1 ||| enter！= 2）时，即使我输入1或2也会不断重复自己的声音吗？

for(d=0;d<3;d++)
    {
    while(sticks>0) {
    System.out.println("Player 1 how many sticks would you like to take? 1 or 2?");
    int  enter = numScan.nextInt();//this tells us how many they're going to take
    sticks=sticks-enter;
    if(enter!=1||enter!=2)//this makes it so people who don't enter a right number are forced to replay the program and suffer
    {
        System.out.println("please run this program again");

    }
    System.out.println("There are "+sticks+" sticks left!");
    System.out.println("Player 2 how many sticks would you like to take? 1 or 2");
    System.out.println("Ther are "+sticks+" sticks left!");
    int enter2=numScan.nextInt();//this is the second enter 
     sticks=sticks-enter2;//this will tell us how many sticks are left 
    if(enter2!=1 || enter2!=2)//this makes it so people who don't enter a right number are forced to replay the program and suffer
    {
        System.out.println("please run this program again");

    }

    System.out.println("Player 1 how many sticks would you like to take? 1 or 2?");
    int enter3=numScan.nextInt();//this is the second enter 
    sticks=sticks-enter3;//this will tell us how many sticks are left 
    System.out.println("There are "+sticks+" sticks left!");
    }
    if(sticks<0||sticks==0)
    {
        System.out.println("The last player who went lost!");
    }
}





}

}

Answer 1

正如comment中所提到的，您在第一局游戏结束后仍然收到相同消息的原因是，sticks的值并没有在结尾处重置（或者游戏开始。

为了解决您的问题，我建议在游戏开始前设置sticks的值，例如：

for(d=0;d<3;d++)
    sticks = 20; //the value with which you initialize the game
    {
    while(sticks>0) {
    System.out.println("Player 1 how many sticks would you like to take? 1 or 2?");
    int  enter = numScan.nextInt();//this tells us how many they're going to take

可能还有其他解决方案。但是通常，您应该在开始时设置游戏的“规则”或“初始化变量”。

Answer 2

if(enter!=1||enter!=2)

更改为

if(enter!=1 && enter!=2) //not easy to understand and requires thinking

if(sticks<0||sticks==0) //equivalent to if(sticks<=0)

为什么不重复三遍？
