我的猜测游戏在一次迭代后就停止了

Question

我的目标是创建一个有三个“玩家”对象的“猜谜游戏”。

我创建了一个名为“target”的变量，其中包含用户的输入。

之后，我对三个“玩家”对象中的每一个运行“猜测”方法，然后运行while循环，直到它被打破。循环中的if语句检查玩家对象的猜测是否等于目标，如果该语句为真，则中断循环。

问题是循环在一次迭代后就停止了。

以下是代码：

import java.util.*;
 class testDrive{
    public static void main(String[] args){
        //code 
        Scanner sc = new Scanner(System.in);
        player p1 = new player();
        player p2 = new player();
        player p3 = new player();
        System.out.println("Enter p1's name:");
        p1.name = sc.nextLine();
        System.out.println("Enter p2's name:");
        p2.name = sc.nextLine();
        System.out.println("Enter p3's name:");
        p3.name = sc.nextLine();
        System.out.println("Enter a number between 0 and 9 for the players to guess");
        int target = sc.nextInt();
        p1.guessing();
        p2.guessing();
        p3.guessing();
        while(true){
            if(target == p1.guess){
                System.out.println(p1.name+" won");
                break;
            }
            else if(target == p2.guess){
                System.out.println(p2.name+" won");
                break; 
            }
            else if(target == p3.guess){
                System.out.println(p3.name+" won");
                break;
            }
            else{
                continue;
            }
        }
}}
 class player{
    int guess;
    String name;
    public void guessing(){
        guess =(int)Math.floor(Math.random() * 9);
        System.out.println(name+"'s guess is "+guess);
    }
}

每次迭代都需要扫描新输入<代码>继续 不会自动执行。

为了在游戏结束时开始一个新游戏，将代码包装在一个无限的当循环中：

import java.util.*;
 class testDrive{
    public static void main(String[] args){
        //code 
        Scanner sc = new Scanner(System.in);
        while(true){
            System.out.println("Starting a new game.");
            player p1 = new player();
            player p2 = new player();
            player p3 = new player();
            System.out.println("Enter p1's name:");
            p1.name = sc.nextLine();
            System.out.println("Enter p2's name:");
            p2.name = sc.nextLine();
            System.out.println("Enter p3's name:");
            p3.name = sc.nextLine();
            System.out.println("Enter a number between 0 and 9 for the players to guess");
            int target = sc.nextInt();
            p1.guessing();
            p2.guessing();
            p3.guessing();
            while(true){
                if(target == p1.guess){
                    System.out.println(p1.name+" won");
                    break;
                }
                else if(target == p2.guess){
                    System.out.println(p2.name+" won");
                    break; 
                }
                else if(target == p3.guess){
                    System.out.println(p3.name+" won");
                    break;
                }
                else{
                    System.out.println("You didn't win. Enter a number between 0 and 9 for the players to guess");
                    target = sc.nextInt();
                }
            }
       }
        
}}
 class player{
    int guess;
    String name;
    public void guessing(){
        guess =(int)Math.floor(Math.random() * 9);
        System.out.println(name+"'s guess is "+guess);
    }
}
