java - 我怎样才能正确打印这个？

Question

这个简单的程序询问玩家的数量，他们的名字，并(在最后一个)计算他们的得分。但我不知道为什么它不转到下一个玩家。看看我的代码:

    Scanner scanner = new Scanner(System.in);
    HashMap<String,Integer> players= new HashMap<String,Integer>();

    System.out.printf("Give the number of the players: ");
    int numOfPlayers = scanner.nextInt();

    for(int k=1;k<=numOfPlayers;k++)
    {
        System.out.printf("Give the name of player %d: ",k);
        String nameOfPlayer= scanner.next();
        players.put(nameOfPlayer,0);//score=0
    }

    //This for finally returns the score 
    for(String name:players.keySet())
    { 
      int k=1;
      do{ 
          System.out.println("Name of player in this round: "+name);
           System.out.printf("Give me your word: ");
           String nameOfWord= scanner.next();

          //::::::::::::::::::::::
          //::::::::::::::::::::::

          int score=players.get(name)+10;
          //This will update the corresponding entry in HashMap
          players.put(name,score);
          System.out.println("The Player "+name+" has "+players.get(name)+" points ");
    }while(k>0);
}
}  }

返回:

 Give the number of the players: 2
 Give the name of player 1: A
 Give the name of player 2: B
 Name of player in this round: A
 Give me your word: ABC
 The Player A has 10 points 
 Name of player in this round: A
 Give me your word:......
........

但是我想在计算“A”的分数后计算“B”的分数。我该怎么做？我做错了什么？

去掉do while - 你不需要它。另外，“正确”地迭代Map。
这是重新设计的代码片段:

// Note this more elegant iteration over a map
for (Map.Entry<String, Integer> entry : players.entrySet()) {
    String name = entry.getKey();
    int score = entry.getValue();
    System.out.println("Name of player in this round: " + name);
    System.out.printf("Give me your word: ");
    String nameOfWord = scanner.next();
    // Some code that uses "nameOfWord"
    score += 10;
    entry.setValue(score); // Note this more elegant use of the API
    System.out.println("The Player " + name + " has " + score + " points");
}

我必须承认我不明白你想要做什么，但至少这段代码达到了你的代码的预期目的。
